The MAX619 step-up charge-pump DC-DC converter delivers a regulated 5V ±4% output at 50mA over temperature. The input voltage range is 2V to 3.6V (two battery cells).The complete MAX619 circuit fits into less than 0.1in² of board space because it requires only four external capacitors: two 0.22µF flying capacitors, and 10µF capacitors at the input and output.Low operating supply current (150µA max) and low shutdown supply current (1µA max) make this device ideal for small, portable, and battery-powered applications. When shut down, the load is disconnected from the input.The MAX619 is available in 8-pin DIP and SO packages.Applications5V Flash Memory ProgrammerBattery-Powered Microprocessor-Based SystemsCompact 5V Op-Amp SupplyLocal 3.3V to 5V ConversionMinimum Component DC-DC ConvertersPortable Instruments and Handy-TerminalsRegulated 5V Supply from Lithium Backup BatteryRemote Data-Acquisition SystemsSwitching Drive Voltage for MOSFETs in Low-Voltage SystemsTwo Battery Cells to 5V Conversion
