Product Summary
The MAX619CSA is a 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 MAX619CSA circuit fits into less than 0.1in2 of board space because it requires only four external capacitors: two 0.22μF flying capacitors, and 10mF capacitors at the input and output. The applications of the MAX619CSA include Two Battery Cells to 5V Conversion, Local 3V-to-5V Conversion, Portable Instruments & Handy-Terminals, Battery-Powered Microprocessor-Based Systems, 5V Flash Memory Programmer, Minimum Component DC-DC Converters, Remote Data-Acquisition Systems, Compact 5V Op-Amp Supply, Regulated 5V Supply from Lithium Backup Battery, Switching Drive Voltage for MOSFETs in Low-Voltage Systems.
