AAT3340, High Efficiency 1x/1.5x Charge Pump

General .
The AAT3340 is a low-noise, constant-frequency charge pump DC/DC converter that uses a dual-mode load switch (1x) and fractional (1.

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
* Automatic Soft Start
* -40°C to +85°C Temperat

Applications

* The AAT3340 is capable of driving 4 white LEDs at a total of 80mA from a single 2.7V to 5.5V input. The current sinks may be operated individually or in parallel while driving higher-current LEDs. A low external parts count (two 1µF flying capacitors and two small 1µF capacitors at VIN and VOUT) ma
