LM2788  
120mA High Efficiency Step-Down Switched Capacitor  
Voltage Converter  
General Description  
Features  
n Output voltage options:  
The LM2788 switched capacitor step-down DC/DC con-  
verter efficiently produces a 120mA regulated low-voltage  
rail from a 2.6V to 5.5V input. Fixed output voltage options of  
1.5V, 1.8V, and 2.0V are available. The LM2788 uses mul-  
tiple fractional gain configurations to maximize conversion  
efficiency over the entire input voltage and output current  
ranges. Also contributing to high overall efficiency is the  
extremely low supply current of the LM2788: 32µA operating  
unloaded and 0.1µA in shutdown.  
2.0V 5%, 1.8V 5%, 1.5V 6%  
n 120mA output current capability  
n Multi-Gain and Gain Hopping for Highest Possible  
Efficiency - up to 90% Efficient  
n 2.6V to 5.5V input range  
n Low operating supply current: 32µA  
n Shutdown supply current: 0.1µA  
n Thermal and short circuit protection  
n Available in an 8-Pin MSOP Package  
The optimal external component requirements of the  
LM2788 solution minimize size and cost, making the part  
ideal for Li-Ion and other battery powered designs. Two 1µF  
flying capacitors and two 10µF bypass capacitors are all that  
are required, and no inductors are needed.  
Applications  
n Cellular Phones  
n Pagers  
The LM2788 also features noise-reducing soft-start circuitry,  
short-circuit protection and over-temperature protection.  
n H/PC and P/PC Devices  
n Portable Electronic Equipment  
n Handheld Instrumentation
