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
external components. In addition, the ADP3607 does not
require the use of an inductor.
The internal oscillator of the ADP3607 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 ADP3607 provides an accuracy of
±
3% with a typical
shutdown current of 2
μ
A. It can also operate from a single
positive 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.
