3.0V to 6.5V input voltage range  
Dual mode operation: 1x and 1.5x  
The CM9156A is an efficient, 1.5x switched capacitor  
(charge pump) regulator ideal for white LED applica-  
tions. It has a regulated 4.5V, 1ꢀ0mA output, capable  
of driving up to six parallel white LEDs. With a typical  
operating input voltage range from 3.0V to 6.0V, the  
CM9156A can be operated from a single-cell Li-Ion  
battery.  
Fixed 4.5V output with initial accuracy of ꢀ2  
Supports up to 180mA (@4V) output  
High efficiency at both high and low input voltages  
Low external parts count, requires no inductor  
PWM brightness control via the ENA pin  
Selectable 8kHz, 3ꢀkHz, ꢀ6ꢀkHz, and 650kHz  
switching frequency  
It features an efficient, 1.5x charge pump circuit that  
uses only two 1.0µF ceramic bucket capacitors and two  
small capacitors for VIN and VOUT. The CM9156A  
offers a selectable switching frequency of 8kHz, 3ꢀkHz,  
ꢀ6ꢀkHz, or 650kHz. The LED brightness can be  
adjusted by applying a PWM signal on the ENA pin.

Low shutdown current of <1µA  
Soft start prevents excessive inrush current  
Over-temperature and over-current protection  
Low output ripple (<12), low EMI  
Input protection provides superior ESD rating  
requiring only standard handling precautions  
TDFN-10 or MSOP-10 package  
The CM9156A output voltage is regulated to 4.5V,  
52 over the line and load ranges. Up 180mA of output  
current is available. The proprietary design architecture  
•
•
Optional RoHS compliant lead free packaging  
maintains high efficiency (> 802), and at low V pro-  
IN  
vides longer battery life. With a high V or when the  
IN,  
Applications  
adapter is powered, it provides cool reliable operation.  
It offers low output voltage ripple, typically less than  
50mV. Internal over-temperature and over-current  
management provide short circuit protection.

Drives white LEDs to backlight color LCDs  
Drives white or RGB LEDs for camera flash  
Cellular phones  
MP3 players  
PDAs, GPS  
The CM9156A is packaged in either a space saving  
10-Lead TDFN or 10-Lead MSOP package. It can  
operate over the industrial temperature range of -ꢀ5°C  
to 85°C.
