TC62D902FG TOSHIBA CD-MOS Integrated Circuit Silicon Monolithic TC62D902FG Offline Isolated AC/DC Flyback LED Controller built-in PFC 1. Overview This product is an isolation type flyback mode LED controller. This device is controlling an average LED current from the primary side current value and the bias side impulse-wave of the transformer and the detection circuit of the secondary side is unnecessary. Then, this product has the active PFC function of the single stage mode and the active bleeder pin to do triac dimmer and realizes LED lighting with few components. 2. Application Isolated AC/DC LED lighting TC62D902FG P-SOP8-0504-1.27-001 Weight : 0.07g（typical） 3. Features  The isolation type LED control with few components  The triac dimmable  Single stage mode PFC  The secondary side photo-coupler is unnecessary.  The bottom switch function for the efficiency and the noise modification  Detection functions  The VCC reduced voltage detection ( UVLO, Under voltage Lockout )  The VIN over-voltage detection ( VIN-OVD )  The sense resistor short detection at Start-Up ( SRSD )  The sense wiring open detection ( SWOD )  The over temperature detection ( OTD )  The output LED open detection ( OOD )  The output LED short detection ( OSD )  The over-current detection at the primary side ( OCD )  Package : P-SOP8-0504-1.27-001 © 2014 TOSHIBA Corporation 1 2014-10-01 4.
