Regulated 3.3V/5.0V Step-Up/Step-Down  
Charge Pump  
MAX195  
General Description  
Features  
The MAX1595 charge-pump regulator generates either  
3.3V or 5V from a 1.8V to 5.5V input. The unique control  
architecture allows the regulator to step up or step down  
the input voltage to maintain output regulation. The  
1MHz switching frequency, combined with a unique  
control scheme, allows the use of a ceramic capacitor  
as small as 1µF for 125mA of output current. The com-  
plete regulator requires three external capacitors—no  
inductor is needed. The MAX1595 is specifically  
designed to serve as a high-power, high- efficiency aux-  
iliary supply in applications that demand a compact  
design. The MAX1595 is offered in space-saving 8-pin  
µMAX® and high-power 12-pin TQFN packages.
