TC62D902FG - Offline Isolated AC/DC Flyback LED Controller built-in PFC

Description

The basic circuit of this product is a flyback power supply.

An average LED current value is controlled by the peak current value ( IS ) of the secondary, and the pulse width ( tS ) and the duty cycle control..

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 ).
