REGULATED CHARGE PUMP
DESCRIPTION
The UTC UCP0510 Charge Pump is a Micro Power switched-capacitor voltage converter that delivers a regulated output. No external inductor is required for operation. Using three small capacitors, the UTC UCP0510 can deliver up to 100mA to the voltage regulated output. The UTC UCP0510 features very low quiescent current and high efficiency over a large portion of its load range making this device ideal for battery-powered applications. Furthermore, the combination of few external components and small package size keeps the total converter board area to a minimum in space restricted applications. The UCP0510 operates in an output-regulated voltage doubling mode. The regulator uses a pulse-skipping technique to provide a regulated output from a varying input supply. The UTC UCP0510 contains a thermal management circuit to protect the device under continuous output short circuit conditions.
