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, V_CC over-voltage protection,
and system output open/short circuit protection to increase IC performance.
