DEVICE DESCRIPTION
TheZXCP330isthefirstinaseriesofswitchedcapacitorDCtoDCconverters,
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
makesthesedevicesidealforlowpowerandbatterypoweredapplications.
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 is also efficient for low current loads.
