AAT3175 | High Efficiency 1X/1.5X/2X Charge Pump For White LED Applications

The AAT3175 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 Flash applications. The AAT3175 is capable of driving up to three Flash LEDs at 300mA total current from a 2.7V to 5.5V input. A low external parts count (two 1F flying capacitors and two small 1F capacitors at VIN and VOUT) make this part ideally suited for small, battery-powered applications. AnalogicTech's S2Cwire (Simple Serial Control) serial digital input is used to enable, disable, and set current for all LEDs with 16 level settings down to 0. The AAT3175 is equipped with built-in protection for VOUT short-circuit condition and auto-disable for load short-circuit condition on any one of the channels. Built-in soft-start circuitry prevents excessive inrush current during start-up. A low-current shutdown feature disconnects the load from VIN and reduces quiescent current to less than 1A. The AAT3175 is available in a Pb-free, space-saving, thermally-enhanced 12-pin 3x3mm TDFN package.
