Z TS19730 Single-Stage Low THD Buck-Boost PWM Control LED Driver SOT-26 Description Pin Definition: 1. VCC 2. GND 3. OUT 4. CL 5. COM 6. CS The TS19730 is a high power factor, low THD and high accuracy constant current PWM controller. TS19730 achieves high power factor and high efficiency by boundary current mode (BCM). The line and load regulation of LED current are within ±2.5%. TS19730 also provides gate driving voltage clamping, VCC over-voltage protection, and system output open/short circuit protection to increase IC performance. Features ● Low THD <10% ● Constant Current Accuracy within ±2.5% ● High Power Factor >0.
