AAT3158 Datasheet - AAT

AAT3158 High Efficiency 1X/1.5X/2X Charge Pump

The AAT3158 is a low noise, constant frequency charge pump DC/DC converter that uses a trimode load switch (1X), fractional (1.5X), and doubling (2X) conversion to maximize efficiency for white LED applications. The AAT3158 is capable of driving up to four LED channels at 20mA per channel from a 2.7.

AAT3158 Features

* ChargePump™ VIN Range: 2.7V to 5.5V Fully Programmable Current with Single Wire

* 16 Current Levels

* Four Low Current Settings Down to 50µA Low IQ (50µA) for Low
