_______________General Desc ription
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.
