LN2114 - High Efficiency 1.5X Fractional Charge Pumps
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.
