Analog Devices ADP3604

The ADP3604 switched capacitor voltage converter provides a regulated output voltage with minimum voltage loss and requires a minimum number of external components. The ADP3604 provides up to 120 mA of output current with ± 3% output accuracy. The internal oscillator runs at 240 kHz nominal frequency which produces an output switching frequency of 120 kHz, allowing the use of small charge pump and filter capacitors.
