JW1780A is a integrate 500V MOS Non-isolated,high output current constant accuracy LED Driver.It realizes high output current constant accuracyby sampling the output current directly. It candecrease MOSFET switching loss and avoidoutside diode reverse recover by switching withboundary mode.
JW1780A is supplied from the output directly and auxiliary winding is not needed.
JW1780A start up time is smaller than 0.1S. It has multi-protection functions which largely enhance the safety and reliability of the system, including VDD UVLO, short-circuit protection, LED open protection and over-temperature protection.
◆Integrate 500V，Low Rdson MOSFET JW1780A: 302, 60mA
◆Excellent line/load regulation
◆LED OVP and SCP
◆Brown Out Protection
