Product Introduction
WD15-S30A is an AC direct LED driver IC with 4 internal steps. It can drive several series of LEDs from rectified AC voltage. It will provide great design convenience because it requires a small number of external components. WD15-S30A has higher LED current driving capability, and its current can be adjusted through an external resistor. WD15-S30A will help engineers produce excellent products in LED lighting energy efficiency, design efficiency, cost efficiency, etc.
