WS3416HD7P – Non-isolated Buck APFC Offline LED Driver IC – DIP-7 Package
The WS3416H is a high precision non-isolated buck driver with active PFC, specially designed for universal input offline constant current LED lighting. The driver with on-chip PFC circuit achieves high power factor and low THD. Operating in critical conduction mode, the power MOSFET switching loss is reduced and the inductor is fully utilized. The WS3416H integrates a 650V power MOSFET. With few external components, the LED output current can be precisely controlled. The WS3416H offers rich protection functions to improve the system reliability, including LED open circuit protection, LED short circuit protection, CS resistor open circuit protection and cycle by cycle current limit. All the protection functions are auto-recovery. The system reliability is further improved by the thermal regulation function. The output current is reduced when the driver is over temperature. The WS3416H has ultra low start up current and ultra low operating current. The WS3416H is available in DIP7 Package.
