MAXIM INTEGRATED / ANALOG DEVICES MAX619CPA Charge Pump Converter
The MAX619 is a compact, high-efficiency charge-pump DC-DC converter designed to generate a stable 5V output from a 2V to 3.6V input, ideal for battery-powered and portable systems. It requires only four small external capacitors—two 0.22uF capacitors for the charge pump and two 10uF capacitors for input and output filtering—making the circuit footprint less than 0.1in2. Operating at 500kHz, it offers over-temperature stable regulation, low quiescent current, and an active shutdown feature for power savings. Suitable applications include microprocessor systems, sensor power supplies, and mobile devices.
