Taiwan Semiconductor
Single-Stage Low THD Buck-Boost PWM Control LED Driver
DESCRIPTION
FEATURES
The TS19730 is a high power factor, low THD and high ● Low THD <10% accuracy constant current PWM controller. TS19730 ● Constant Current Accuracy within ±2.5% achieves high power factor and high efficiency by ● High Power Factor >0.9 discontinuous conduction mode (DCM). The line and ● Low BOM Cost load regulation of LED current are within ±2.5%. ● Discontinuous Conduction Mode Control TS19730 also provides gate driving voltage clamping, ● Gate Output Voltage Clamp VCC over-voltage protection, and system output ● LED Open Protection open/short circuit protection to increase IC performance.
