TS19751 Taiwan Semiconductor Single-Stage Buck Current Control LED Driver with High Voltage MOSFET Integrated DESCRIPTION The TS19751 is a high performance LED driver which accuracy constant current PWM controller with high voltage power MOSFET integrated. It achieves high accuracy by peak current mode. The device provide high efficiency along with a number of key built-in protection features while minimizing the external component count, simplifying EMI design and lowering the total bill of material cost. TS19751 also achieving excellent line and load regulation. Pulse-by-pulse waveform analysis allows for a loop response that is much faster than traditional solutions, resulting in improved dynamic load response. The built-in current limit function enables optimized transformer design in universal off-line applications over a wide input voltage range.
