OB3655x High Precision Offline LED Lighting Power Switch GENERAL DESCRIPTION OB3655x is an offline LED lighting controller with high constant current (CC) precision. It can achieve low system cost for an isolated lighting application by primary side control in a single stage converter. It significantly simplifies the LED lighting system design by eliminating auxiliary winding. The system uses the Quasi-Resonant (QR) operation and clamping frequency greatly improves the system efficiency. The advanced start-up technology is used to meet the start-up time requirement (<0.5s). The constant output current is compensated for tolerance of transformer inductance variation. And the line compensation and load compensation are built in OB3655x for high precisely constant output current control.
