ZXCP330 - Zetex Semiconductors

ZXCP330 SWITCHED CAPACITOR DC-DC CONVERTER

The ZXCP330 is the first in a series of switched capacitor DC to DC converters, converting an input voltage from between 2 volts and 4.4 volts to a regulated output voltage of 3.3V with a maximum load current of 40mA. The device operates with one flying capacitor and two small bypass capacitors at input and output making for a very small solution. Very low q.
