GENERAL DESCRIPTION

The ADP3605 is a 120 mA regulated output switched capacitor

voltage inverter. It provides a regulated output voltage with

minimum voltage loss and requires a minimum number of ex-

ternal components. In addition, the ADP3605 does not require

the use of an inductor.

Pin-for-pin and functionally compatible with the ADP3604, the

internal oscillator of the ADP3605 runs at 500 kHz nominal

frequency which produces an output switching frequency of

250 kHz. This allows for the use of smaller charge pump and

filter capacitors.

The ADP3605 provides an accuracy of 3% with a typical shut-

down current of 2 A. It can also operate from a single positive

input voltage as low as 3 V. The ADP3605 is offered with the

regulation fixed at –3 V or adjustable via external resistors over

a –3 V to –6 V range.
