Overview
General Description
The AAT3340 is a low-noise, constant-frequency charge pump DC/DC converter that uses a dual-mode load switch (1x) and fractional (1.
5x) conversion to maximize efficiency for white LED 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) makes the AAT3340 ideal for small battery-powered applications.
Skyworks' Simple Serial Control (S2Cwire) digital interface is used to enable, disable and set current to one of 32 level...
