AAT3157 High Efficiency 1X/1.5X/2X Charge Pump

The AAT3157 is a low noise, constant frequency charge pump DC/DC converter that uses a tri-mode load switch (1X), fractional (1.5X), and doubling (2X) conversion to maximize efficiency for white LED applications. The AAT3157 is capable of driving up to three channels of LEDs at 20mA per channel from.

AAT3157 Features

* 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 Current Mode

* Tri-Mode 1X, 1.5X, and 2X Charge Pump for Maximum Efficiency and VF Coverage

* Drives up
