G5910

High-Efficiency White LED Charge Pump

Features

General Description

ꢀ

Input Range：2.7V to 5V

Quiescent Current: 90ꢀA

Regulated 5V ±4% Output

5V Output Current

The G5910 Charge-Pump is a switched-capacitor

voltage converter that delivers a regulated output. The

external inductor is not required for operation. Using

small capacitors, the G5910 can deliver up to 90mA

(@V_IN=3V) to the voltage-regulated output. The G5910

features high efficiency over a large portion of its load

range making this device ideal for battery-powered

applications. The combination of few external compo-

nents and small package size keeps the total con-

verter board area to a minimum in space-restricted

applications. The G5910 contains a thermal manage-

ment circuit to protect the device under continuous

output short circuit conditions.
