IXD2110/IXD2111  
Step-Up DC/DC Converter / Controller  
step-up operation by using only an inductor, a  
capacitor, and a diode connected externally.  
FEATURES  
o
o
Operating Input Voltage Range: 0.9V ~ 10.0V  
Output Voltage Range: 1.5V~7.0V with (0.1V  
increments, accuracy ±2.5%)  
The IXD2110/111B, D, and F versions can be used  
with an external transistor for applications requiring  
larger currents.  
o
o
Maximum Oscillation Frequency: 100 kHz  
(180kHz for the IXD2111)  
Built-in Switching NMOSFET (A/C/E type) or  
External Transistor (B/D/F type)  
Output voltage is internally programmed in a range  
from 1.5V to 7.0V in increments of 0.1V (accuracy  
± 2.5%).  
o
o
Low Operating Supply Current: 2.0µA  
Small Package: SOT-23 & SOT89 (for IXD2111  
series),SOT-25, USP-6C 8-pin 2 x 3 x 0.8 mm  
TDFN package  
Maximum oscillation frequency is set to 100 kHz for  
IXD2110/111 series. (At light loads, it is set to  
180 kHz for the IXD2111 series.)  
Options include products equipped with a CE pin (C  
and D versions) that allows the IC to be shut down,  
thereby reducing supply current, and with separated  
VDD/VOUT pins (E and F versions) to separate the  
power supply block and the output voltage detect  
block.  
APPLICATION  
o
o
o
Mobile phones  
Cameras, VCRs  
Various portable equipment  
With the IXD2110 series, maximum duty cycle is set  
to 75% (VDD = 3.3 V) making it suitable for use with  
large current operations. The IXD2111 series  
automatically switches duty ratio between 56% &  
75% (VDD = 3.3 V) to drop output ripple voltage, when  
it senses changes in load, It can support both large  
and small currents.  
DESCRIPTION  
The IXD2110/IXD2111 series is a group of PFM step-  
up DC/DC converter/controller ICs, designed to  
generate low supply voltage. The series is ideal for  
applications where a longer battery life is needed  
such as in portable communication equipment. With a  
The external transistor types (B/D/F types) designed  
for applications, which require larger currents.  
built-in 2.5

power consumption. Please refer to Input Current (IIN) under no load condition for the actual current, which is supplied from the input power  
supply (VIN).

*4: The Lx limit voltage function becomes stable when VOUT is over 2.0 V.

NOTE:  
*1: "Supply Current 1" is the value when the IC is constantly switching. In actual operation, the oscillator periodically switches, resulting in lower  
power consumption.  
*2: EXT “H” ON resistance can be calculated by (0.4 x Rp) / (VEXT - Vpull). * Change Vpull so that VEXT will become VOUT - 0.4 V.  
*3: EXT “L” ON resistance can be calculated by (VEXT x Rp) / (Vpull - VEXT). * Change Vpull so that VEXT will become 0.4 V.  
*4: EFFI = {[output voltage] × (output current)} / [(input voltage) × (input current)] ×100  
*5: When using VDD and VOUT separately, please, set the voltage range of VDD from 1.5 V to 10 V. The IC operates from VDD = 0.8V, but output  
voltage and oscillation frequency will be stable when VDD = 1.5 V or more.

The IXD2110 series' duty cycle ratio is 75% at oscillation frequency  
(fOSC) 100 kHz. The duty ratio of the IXD2111 series automatically  
varies between 56% at oscillation frequency 180 kHz and 75% at

* The duty ratio depends on power supply. Please refer to the  
electrical characteristics on duty cycle against output voltage you use.  
BASIC OPERATION  
The IXD2110/111 series are PFM mode step-up DC/DC converters (A, C and E types) / controllers ICs (B, D and F  
types), which contain voltage reference source Vref, PFM Comparator, Duty Cycle Selector, PFM controlled  
Oscillator, VLx Voltage Limiter, Buffer, and MOSFET transistor.  
Maximum duty cycle ratio of 75% at oscillation frequency 100 kHz for IXD2110 series makes it suitable for use with  
large load current.  
The IXD2111 series automatically switches duty cycle ratio between 56% at oscillation frequency 180 kHz and 75%  
at oscillation frequency 100 kHz, when it senses changes in load, and it can support both large and small load  
currents.  
Reference Voltage Source (Vref)  
The reference voltage source provides the reference voltage to ensure stable output voltage of the DC/DC  
converter.  
PFM Comparator  
The PFM comparator compares the feedback voltage divided by the internal resistive divider with the internal  
reference voltage. When the feedback voltage is higher than the reference voltage, PFM controlled oscillator will be  
stopped. When the feedback voltage is lower than the reference voltage, the PFM controlled oscillator sends  
through buffer a signal to the internal or external switching transistor to keep output voltage stable.  
Duty Cycle Selector  
With the IXD2111 series, the duty cycle selector automatically switches duty cycle ratio between 56% and 75%  
when it senses changes in load to support both large and small currents.  
PFM Controlled Oscillator  
The PFM controlled oscillator determines maximum oscillation frequency. The circuit generates the oscillation  
frequency of 100 kHz at 75% duty cycle and 180 kHz at 56%.  
VLx Voltage Limiter  
The VLx circuits of the ISD110/111 A, C, and D types detect in-rush current and over-current, which flows from the  
VOUT pin to the Lx pin. In case of over-current, the switching transistor will be OFF. When the over-current condition  
removed, the IC resumes its normal operation.

Chip Enable Function  
The chip enable function of the IXD2110/111 C and D types sends IC into shut down mode, when CE pin is logic  
low. The current consumption in shutdown mode is less than 0.5 µA.  
Separated VDD/VOUT  
Additional VDD pin allows IXD2110/111 E and F types operate with VOUT voltage higher or lover than VDD voltage  
reguired for stable IC operations.

EXTERNAL COMPONENTS  
The IXD2110/111 B/D/F type allows use of the n-channel MOSFET or n-p-n transistor as external switch.  
In case of a MOSFET, recommended type is XP151A13A0MR-G from TOREX.  
Note:  
VGS breakdown voltage of this transistor is 8 V. If the power supply voltage is above 6 V use XP151A12A2MR-G  
with a VGS breakdown voltage of 12 V.  
In case of n-p-n transistor, recommended type is 2SD1628 from SANYO with RB 500 Ω (Adjust in accordance with  
load and transistors hFE.), and CB 2200pF. CB ≤1 / (2TT x RB x FOSC x 0.7)  
Recommended RB values for low input voltages are show in the table below.

Other recommended components are:  
Diodes XBS104S14R-G from TOREX, or MA2Q735 from MATSUSHITA  
Output capacitor COUT 16V, 47 µF TAJ type from KYOCERA  
Input capacitor CIN 16V, 47 µF TAJ type from KYOCERA, or 16V, 220 µF (electrolytic capacitor)  
Inductor L for IXD2110/111A, C, and E series with built-in transistor 100 µH CR54, or CDRH6D28 type from  
SUMIDA  
Inductor L for IXD2110/111B, D, and F series with external transistor 22 µH or 47µH CR54 type from SUMIDA  
LAYOUT AND USE CONSIDERATIONS  
1. Please, do not exceed the value of stated absolute maximum ratings.  
2. The DC/DC converter / controller IC's performance is greatly influenced by not only the ICs' characteristics, but  
also by those of the external components. Care must be taken when selecting external components.  
3. The Lx limit voltage function becomes stable when VOUT of the IXD2110/111C series is over 2.0V and the VDD  
of the IXD2110/111E series is over 2.0V.  
4. Make sure that the PCB ground traces are as thick as possible, as variations in ground potential caused by  
high ground currents at the time of switching may result in instability of the IC.  
5. Please, mount each external component as close to the IC as possible and use thick, short connecting traces  
to reduce the circuit impedance.
