TS19452 Datasheet | Taiwan Semiconductor

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...
