Product Introduction
WD35-S28A is an AC direct LED driver integrated circuit with internal 2 channels and external 2 channels. It can drive several series of LEDs from rectified AC voltage. It will provide great convenience in design because it requires a small number of external components. WD35-S28A has higher LED current driving capability, and the current can be adjusted through external resistors. WD35-S28A will help engineers produce excellent products in LED lighting energy efficiency, design efficiency, cost efficiency, etc.
