Description
The WS3413E 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 WS3413E integrates a 550V power MOSFET. With
few external components, the LED output current can be
precisely controlled.
The WS3413E 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 WS3413E has ultra low start up current and ultra low
operating current.
The WS3413E is available in DIP7/SOP7 Package.
