• AL3159FSG-EVM Rev.1, Evaluation Module for the AL3159 is a low noise, constant frequency charge pump DC/DC converter that uses a dual mode load switch (1x) and (2x) conversion for white LED applications. The AL3159 is capable of driving three groups of three LED channels at 20mA from a 2.7V to 5.5V input. The current sinks may be operated using three simple logic control inputs individually or in parallel for driving higher current LEDs
