ZXCP330 SWITCHED CAPACITOR DC-DC CONVERTER DEVICE DESCRIPTION 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 quiescent current makes these devices ideal for low power and battery powered applications.
Regulation is achieved by sensing the output and enabling the device charge pump when it falls below the sense threshold.
This technique leads to high efficiency conversion.
The method i...
