GENERAL DESCRIPTION
The ADP3607 is a 50 mA regulated output switched capacitor
voltage doubler. It provides a regulated output voltage with
minimum voltage loss and requires a minimum number of ex-
ternal components. In addition, the ADP3607 does not require
the use of an inductor.
The internal oscillator of the ADP3607 runs at 500 kHz nomi-
nal frequency, which produces an output switching frequency of
250 kHz. This allows for the use of smaller charge pump and
filter capacitors.
The ADP3607 provides an accuracy of
±
5% with a typical shut-
down current of 150
μ
A. It can also operate from a single posi-
tive input voltage as low as 3 V. The ADP3607 is offered with
the regulation fixed at 5 V, or adjustable via external resistors
over a 3 V to 9 V range.
