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
μ
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.
