5X/2X Charge Pump For White LED Applications General Description The AAT3153 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 AAT3153 is capable of driving sixchannel LEDs from a 2.
7V to 5.
5V input.
The current sinks may be operated individually or in parallel for driving higher-current LEDs.
Low external parts count (two 1µF flying capacitors and two small 1µF capacitors at VIN and VOUT) makes 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 each LED with eight settings (20mA down to 50µA) including main and sub-display group control.
The AAT3153 consumes extremely low current internally (40µA typical) at light load for optimized efficiency.
