OB3652P Description
OB3652P is a primary side control offline LED lighting controller with very low operation current which can achieve accurate LED current for an isolated lighting application in a single stage converter. It significantly simplifies the LED lighting system design by eliminating the secondary side feedback ponents and the opto-coupler, and also the auxiliary winding inductance. A HV 600V power switch is also integrated...
