19-2107; Rev 1; 8/02

Regulated 3.3V/5.0V Step-Up/Step-Down

Charge Pump

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 complete regulator requires three external capaci-

tors—no inductor is needed. The MAX1595 is specifi-

cally designed to serve as a high-power, high-

efficiency auxiliary supply in applications that demand

a compact design. The MAX1595 is offered in space-

saving 8-pin µMAX and high-power 12-pin thin QFN

packages.
