JW®1827 is an offline step-down LED controller adaptive for PWM dimming.
High output constant current accuracy is achieved with optimized sampling technics. Critical conduction mode ensures high efficiency and good EMI performance.
JW1827 is supplied from line voltage directly without auxiliary winding and start-up circuitry, which can lower the system BOM cost.
JW1827 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.
