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

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 capacitors—no inductor is needed. The MAX1595 is specifically 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 TQFN packages.Applications3.3V to 5V Local Conversion Applications3V to 5V GSM SIMM CardsBackup Battery Boost ConvertersBattery-Powered ApplicationsFlash Memory SuppliesMiniature EquipmentPCMCIA CardsWhite LED Power
