Regulated 5V Charge-Pump
DC-DC Converter
_______________General Description
The MAX619 step-up charge-pump DC-DC converter
delivers a regulated 5V ±4% output at 50mA over tem-
perature. The input voltage range is 2V to 3.6V (two
battery cells).
The complete MAX619 circuit fits into less than 0.1in 2 of
board space because it requires only four external
capacitors: two 0.22 μ F flying capacitors, and 10 μ F
capacitors at the input and output.
Low operating supply current (150 μ A max) and low
shutdown supply current (1 μ A max) make this device
ideal for small, portable, and battery-powered applica-
tions. When shut down, the load is disconnected from
the input.
The MAX619 is available in 8-pin DIP and SO packages.
