Datasheet Summary
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...
