Overview
19-0227; Rev 2; 5/96 NUAL KIT MA ATION EET H S A EVALU T WS DA FOLLO Regulated 5V Charge-Pump DC-DC Converter ____________________________Features o Regulated 5V ±4% Charge Pump o Output Current Guaranteed over Temperature 20mA (VIN ≥ 2V) 50mA (VIN ≥ 3V) o 2V to 3.
6V Input Range o No Inductors; Very Low EMI Noise o Ultra-Small Application Circuit (0.
1in2) o Uses Small, Inexpensive Capacitors o 500kHz Internal Oscillator o Logic-Controlled 1µA Max Shutdown Supply Current o Shutdown Disconnects Load from Input o 8-Pin DIP and SO Packages _______________General Description 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.
22µ F flying capacitors, and 10µ F capacitors at the input and output.
Low operating supply current (150 µA 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.
