Single-Stage Buck Current Control LED Driver
with High Voltage MOSFET Integrated
DESCRIPTION
The TS19751 is a high performance LED driver
wh
ich 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.
