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 ±5 with a typical shutdown current of 150 µA. 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.
