AAT3159 | High Efficiency 1X/1.5X/2X Charge Pump For White LED Applications

The AAT3159 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 device is capable of driving up to four channels of LEDs at up to 40mA per channel from a 2.7V to 5.5V input supply voltage. The current sinks may be operated individually or in parallel for driving higher-current LEDs A low external parts count (two 1F flying capacitors [C1 and C2] and two small 1F capacitors [C
