Description  
The QSK033A0B series of dc-dc converters are a new generation of DC/DC power modules designed to support  
12Vdc intermediate bus applications where multiple low voltages are subsequently generated using point of load  
(POL) converters. The QSK033A0B series are enhanced from their predecessor QBK033A0B series, with  
improvements to the internal shutdown control, improved response to input voltage transients, and inclusion of output  
reverse current protection during startup. The QSK033A0B series operate from an input voltage range of 36 to 60Vdc  
and provide up to 33A output current at 12V in an industry standard quarter brick. The converter incorporates  
synchronous rectification technology and innovative packaging techniques to achieve efficiency reaching 94% at 12V  
full load. This leads to lower power dissipations such that for many applications a heat sink is not required.  
The output is fully isolated from the input, allowing versatile polarity configurations and grounding connections. Built-  
in filtering for both input and output minimizes the need for external filtering.

CAUTION: This power module is not internally fused. An input line fuse must always be used.  
This power module can be used in a wide variety of applications, ranging from simple standalone operation to an  
integrated part of sophisticated power architecture. To preserve maximum flexibility, internal fusing is not included,  
however, to achieve maximum safety and system protection, always use an input line fuse. The safety agencies  
require a fast-acting fuse with a maximum rating of 30 A (see Safety Considerations section). Based on the  
information provided in this Data Sheet on inrush energy and maximum dc input current, the same type of fuse with a  
lower rating can be used. Refer to the fuse manufacturer’s Data Sheet for further information.

Test Configurations  
Design Considerations  
Input Source Impedance  
The power module should be connected to a low  
ac-impedance source. A highly inductive source  
impedance can affect the stability of the power module.  
For the test configuration in Figure 9, a 330μF  
electrolytic capacitor, Cin, (ESR<0.7Ω at 100kHz),  
mounted close to the power module helps ensure the  
stability of the unit. Consult the factory for further  
application guidelines.  
Safety Considerations  
Note: Measure input reflected-ripple current with a simulated  
source inductance (LTEST) of 12 µH. Capacitor CS offsets  
possible battery impedance. Measure current as shown above.  
Figure 9. Input Reflected Ripple Current Test Setup.  
For safety-agency approval of the system in which the  
power module is used, the power module must be  
installed in compliance with the spacing and separation  
requirements of the end-use safety agency standard,  
i.e., UL60950-1, CSA C22.2 No. 60950-1, and VDE  
EN60950-1.  
If the input source is non-SELV (ELV or a hazardous  
voltage greater than 60 Vdc and less than or equal to  
75Vdc), for the module’s output to be considered as  
meeting the requirements for safety extra-low voltage  
(SELV), all of the following must be true:  
ƒ
The input source is to be provided with reinforced  
insulation from any other hazardous voltages,  
including the ac mains.  
ƒ
One VIN pin and one VOUT pin are to be grounded, or  
both the input and output pins are to be kept  
floating.  
Note: Use a 1.0 µF ceramic capacitor and a 10 µF aluminum or  
tantalum capacitor. Scope measurement should be made  
using a BNC socket. Position the load between  
ƒ
ƒ
The input pins of the module are not operator  
accessible.  
Another SELV reliability test is conducted on the  
whole system (combination of supply source and  
subject module), as required by the safety agencies,  
to verify that under a single fault, hazardous  
voltages do not appear at the module’s output.  
51 mm and 76 mm (2 in. and 3 in.) from the module.  
Figure 10. Output Ripple and Noise Test Setup.  
Note: Do not ground either of the input pins of the  
module without grounding one of the output pins.  
This may allow a non-SELV voltage to appear  
between the output pins and ground.  
CONTACT AND  
DISTRIBUTION LOSSES

The power module has safety extra-low voltage (SELV)  
outputs when all inputs are SELV.

The input to these units is to be provided with a

unearthed lead.

Note: All measurements are taken at the module terminals.  
When socketing, place Kelvin connections at module terminals  
to avoid measurement errors due to socket contact resistance.

Output Overvoltage Clamp  
Feature Descriptions  
The output overvoltage clamp consists of a control  
circuit, independent of the primary regulation loop, that  
Overcurrent Protection  
To provide protection in a fault output overload condition,  
the module is equipped with internal current-limiting  
circuitry and can endure current limiting for a few mili-  
seconds. If the overcurrent condition persists beyond a  
few milliseconds, the module will shut down and remain  
latched off. The overcurrent latch is reset by either  
cycling the input power or by toggling the on/off pin for  
one second. If the output overload condition still exists  
when the module restarts, it will shut down again. This  
operation will continue indefinitely until the overcurrent  
condition is corrected.  
monitors the voltage on the output terminals and clamps  
the voltage when it exceeds the overvoltage set point.  
The control loop of the clamp has a higher voltage set  
point than the primary loop. This provides a redundant  
voltage control that reduces the risk of output  
overvoltage.  
Overtemperature Protection  
These modules feature an overtemperature protection  
circuit to safeguard against thermal damage. The circuit  
shuts down and latches off the module when the  
maximum device reference temperature is exceeded.  
The module can be restarted by cycling the dc input  
power for at least one second or by toggling the remote  
on/off signal for at least one second.  
An auto-restart option is also available. An auto-restart  
feature continually attempts to restore the operation until  
fault condition is cleared.  
Remote On/Off  
Input Under/Over voltage Lockout  
Two remote on/off options are available. Positive logic  
remote on/off turns the module on during a logic-high  
voltage on the ON/OFF pin, and off during a logic low.  
Negative logic remote on/off turns the module off during  
a logic high and on during a logic low. Negative logic,  
device code suffix "1," is the factory-preferred  
At input voltages above or below the input under/over  
voltage lockout limits, module operation is disabled. The  
module will begin to operate when the input voltage level  
changes to within the under and overvoltage lockout  
limits.  
configuration. The on/off circuit is powered from an  
internal bias supply. To turn the power module on and  
off, the user must supply a switch to control the voltage  
between the on/off terminal and the Vi (-) terminal  
(Von/off). The switch can be an open collector or  
equivalent (see Figure 12). A logic low is Von/off = -0.3V  
to 0.8V. The typical Ion/off during a logic low is 10 µA.  
The switch should maintain a logic-low voltage while  
sinking 10µA. During a logic high, the maximum Von/off  
generated by the power module is 3.5V. The maximum  
allowable leakage current of the switch at Von/off = 2.0V  
is 4µA. If using an external voltage source, the maximum  
voltage V on/off on the pin is 13.5V with respect to the  
Vi (-) terminal.  
Active Load Sharing (Parallel Operation with  
–P option)  
For additional power requirements, the power module  
can be configured for parallel operation with active load  
sharing. Good layout techniques should be observed  
for noise immunity when using multiple units in parallel.  
To implement active load sharing, the following  
requirements should be followed:  
•
The share pins of all units in parallel must be  
connected together. The path of these connections  
should be as direct as possible. Vin(-) is the return  
for the active share signal for each module;  
If not using the remote on/off feature, perform one of the  
following to turn the unit on:  
therefore, all modules in parallel must use the same  
Vin source. The share signal trace should be placed  
as close to the Vin(-) power plane as possible.  
For negative logic, short ON/OFF pin to VI(-).  
For positive logic: leave ON/OFF pin open.  
•
•
•
These modules contain circuitry to block reverse  
current flow upon start-up, when output voltage is  
present from other parallel modules, eliminating the  
requirement for external output ORing devices.  
However, output ORing devices should be used, if  
fault tolerance is desired in parallel applications.

Feature Descriptions (continued)  
Thermal Considerations  
Although the maximum THx temperature of the power  
modules is 110°C - 125°C, you can limit this temperature  
to a lower value for extremely high reliability.  
The power modules operate in a variety of thermal  
environments and sufficient cooling should be provided  
to help ensure reliable operation.  
Please refer to the Application Note “Thermal  
Characterization Process For Open-Frame Board-  
Mounted Power Modules” for a detailed discussion of  
thermal aspects including maximum device  
temperatures.  
Thermal considerations include ambient temperature,  
airflow, module power dissipation, and the need for  
increased reliability. A reduction in the operating  
temperature of the module will result in an increase in  
reliability. The thermal data presented here is based on  
physical measurements taken in a wind tunnel.  
Heat Transfer via Convection  
Heat-dissipating components are mounted on the top  
side of the module. Heat is removed by conduction,  
convection and radiation to the surrounding environment.  
Proper cooling can be verified by measuring the thermal  
reference temperature (THx). Peak temperature (THx)  
occurs at the position indicated in Figure 13 and Figure  
14. For reliable operation this temperature should not  
exceed the listed temperature threshold.  
Increased airflow over the module enhances the heat  
transfer via convection. The thermal derating figures  
(15-17) show the maximum output current that can be  
delivered by each module in the respective orientation

RoHS-compliant through-hole products can be  
processed with paste-through-hole Pb or Pb-free reflow  
process. If additional information is needed, please  
consult with your Lineage Power representative for more  
details.  
Layout Considerations  
The QSK033 power module series are low profile in  
order to be used in fine pitch system card architectures.  
As such, component clearance between the bottom of  
the power module and the mounting board is limited.  
Avoid placing copper areas on the outer layer directly  
underneath the power module. Also avoid placing via  
interconnects underneath the power module.  
Post Solder Cleaning and Drying  
Considerations  
Post solder cleaning is usually the final circuit-board  
assembly process prior to electrical board testing. The  
result of inadequate cleaning and drying can affect both  
the reliability of a power module and the testability of the  
finished circuit-board assembly. For guidance on  
appropriate soldering, cleaning and drying procedures,  
refer to Lineage Power Board  
For additional layout guide-lines, refer to FLTR100V10  
Data Sheet.  
Through-Hole Lead-Free Soldering  
Information

components. They are designed to be processed  
through single or dual wave soldering machines. The  
pins have an RoHS-compliant finish that is compatible  
with both Pb and Pb-free wave soldering processes. A  
maximum preheat rate of 3°C/s is suggested. The wave  
preheat process should be such that the temperature of  
the power module board is kept below 210°C. For Pb  
solder, the recommended pot temperature is 260°C,  
while the Pb-free solder pot is 270°C max. Not all
