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 1F 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
MAX and high-power 12-pin TQFN packages.
