Overview

SOT-89 Pin Definition: 1.
Drain 2.
GND 3.
VDD TS19451 AC/DC WLED Driver with Internal MOSFET Universal Switch Mode General Description The TS19451 is a PWM high efficiency LED driver control IC.
It allows efficient operation of LED strings from voltage source ranging up to 400VDC.
It includes an internal high voltage switching MOSFET controlled with fixed off-time of approximately 10.
5µS.
The LED string is driven at constant current, thus providing constant light output and enhanced reliability.
The output current is internally fixed at 50mA.
The peak current control scheme provides good regulation of the output current throughout the universal AC line voltage range of 85~264VAC or DC inp...
