TS19452CS

TS19452 AC/DC WLED Driver with Internal MOSFET Universal Switch Mode SOP-8 Pin assignment: 1. Drain 8. Ground 2. Drain 7. Ground 3. Drain 6. Ground 4. Vdd 5. Ground General Description The TS19452 is a PWM high efficiency LED driver control IC. It allows efficient operation of LED strings from voltage source ranging up to 450VDC. It includes an internal high voltage switching MOSFET controlled with fixed off-time of approximately 12µS. The LED string is driven at constant current, thus providing constant light output and enhanced reliability. The output current is internally fixed at 100mA. The peak current control scheme provides good regulation of the output current throughout the universal AC line voltage range of 85~264VAC or DC input voltage of 20~400V Features ● ● ● ● ● Constant output current at 100mA(typ) Universal 85~264VAC operation Fixed off-time buck converter Internal 475V power MOSFET Low inductance value at 4.7mH (typ) Typical Application Circuit Application ● ● Decorating LED lighting LED lamps with AC or DC operation.
