General Description

The LN2113 and LN2114 are low noise, constant frequency charge pump DC/DC converters that use fractional (1.5X) conversion to increase efficiency in white LED applications.

The devices can be used to produce current levels up to 20mA for each output from a 2.7V to 5.5V input.

A low external parts count (two 1μF flying capacitors and two small bypass capacitors at VIN and OUT) makes the LN2113/LN2114 ideally suited for small battery-powered applications.
