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.
