General Description
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.
