Single-Stage Low THD Buck-Boost PWM Control LED Driver TS19730CX6



The TS19730 is a cost-effective AC-DC LED driver with integrated power factor correction (PFC), THD less than 10%, and constant current output load regulation to within ±2.5%.

It operates in boundary conduction mode (BCM) to achieve PFC greater than 0.9 and high efficiency conversion. TS19730 also provides voltage clamp protection for the gate driving output, VCC over-voltage protection, and system output open/short circuit protection.

The application range for this LED driver includes LED lighting power up to 30 W for down-light, tube, and PAR lamp applications. An application note with reference design, demo board and recommended BOM will be available.
