Regulated 3.3V/5.0V Step-Up/Step-Down Charge Pump MAX1595 General Description Features
The MAX1595 charge-pump regulator generates either o
Ultra-Small: Requires Only Three Ceramic
3.3V or 5V from a 1.8V to 5.5V input. The unique control
Capacitors
architecture allows the regulator to step up or step down the input voltage to maintain output regulation. The o
No Inductors Required
1MHz switching frequency, combined with a unique o
Up to 125mA Output Current
control scheme, allows the use of a ceramic capacitor as small as 1µF for 125mA of output current. The com- o
Regulated ±3% Output Voltage
