DESCRIPTION
The UTC L5201-xx series are low noise, constant frequency charge pump DC/DC converters and designed to increase efficiency in white LED application. The operating voltage range is 2.7V ~ VOUT input with up to 100mA of output current. Low external parts counts (one flying capacitor and two small bypass capacitors at VIN and VOUT) make the UTC L5201-xx series ideally suited for small, battery-powered applications.
