High-Efficiency Charge Pump LED Driver based on Diodes Solution

This evaluation board demonstrates Diodes' AL3157s ability to control the LED current and perform PWM dimming. The AL3157 is a low noise, constant frequency charge pump DC/DC converter that uses a dualmode load switch (1x) and doubling (2x) conversion for white LED applications. The PWM signals are generated by an on-board microcontroller with three push buttons for adjusting current levels.
