AAT3340 Description

PRODUCT DATASHEET www.DataSheet4U.com AAT3340 TM ChargePump High Efficiency 1x/1.5x Charge Pump .
The AAT3340 is a low-noise, constant-frequency charge pump DC/DC converter that uses a dual-mode load switch (1x) and fractional (1.

AAT3340 Features

* Dual-Mode (1x/1.5x) Charge Pump
* Drives up to 4-Channel Backlight LEDs
* 32-Level Programmable Backlight Current (linear, inverting)
* Single-wire S2Cwire Control
* Built-in Thermal Protection
