OB3652P High Precision Offline LED Power Switch GENERAL 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 components and the opto-coupler, and also the auxiliary winding inductance. A HV 600V power switch is also integrated into the device. The LED current can be adjusted externally by the sense resistor Rs at CS pin and high precision constant current regulation is realized.
