On-Bright OB3652PAP
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. The LED current can be adjusted externally by the sense resistor Rs at CS pin and high precision constant current regulation is realized.| Part No. | OB3652PAP |
