  • Description
    JW®1827B is an offline step-down LED driver adaptive for PWM dimming with high voltage MOS integrated. 
    High output constant current accuracy is achieved with optimized sampling technics. Critical conduction mode ensures high efficiency and good EMI performance. 
    JW1827B is supplied from line voltage directly without auxiliary winding and start-up circuitry, which can lower the system BOM cost. 
    JW1827B has multi-protection functions which largely enhance the safety and reliability of the system, including VDD UVLO, Vin UVLO, LED short protection and over-temperature protection.
