5 Watt Single Output, 5V Input Series DC/DC Converters  
Description  
Features  
The CALEX 5 Watt DC/DC converters are ideal for use in high  
performance computer data acquisition systems and board  
level products. They are designed for systems that require a  
regulated and isolated 5, 12 or 15 Volt auxiliary power source.  
n
Low Profile Copper Case (0.375" High)  
n
Six-side Shielded Case  
n
Low Input/Output Noise Operation  
The converters have efficiencies typically greater than  
60%. A linear post regulator provides highly stable DC  
outputs while minimizing noise.  
n
Wide Input Voltage Range  
n
Highly Regulated/Low Drift Output  
n
Every unit is 100% tested prior to shipment and is  
guaranteed under the CALEX 5 Year Warranty.

5 Watt WF Single Output Series DC/DC Converters  
Description  
Features  
This single output converter is designed for wide input range,  
n
Ultra Wide Input Voltage Range  
low noise industrial and instrument applications. The ultra  
wide isput range is ideal for battery or unregulated input  
applications.  
n
n
n
n
Low Noise, Trimable, Highly Stable Output  
Efficiency > 74% For All Line Conditions  
No Derating to 80°C Case Temperature  
The converter features a 55kHz switching frequency that  
provides outstanding regulation and efficiency at full load.  
Six-sided Shielded, Low Thermal Gradient  
Copper Case  
The output is regulated with high loop gain pulse width  
modulation control which provides linear regulator type  
performance.  
n
n
Overvoltage Protected Output  
The output is resistor or trimpot trimable by ±10%, which  
allows th WF to be set for +5.2 VDC in ECL applications.  
Pulse By Pulse Digital Current Limit  
The WF is protected from output shorts to ground by a high  
speed digital, current limit circuit. The output is oervoltage  
protected.
