WS3413 ProductDescription

Non-isolated Buck APFC Offline LED Driver

Features



Internal 550V Power MOSFET

Active PFC for High Power Factor and Low THD

Critical Conduction Mode Operation

System Efficiency up to 95%

Description

The WS3413 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.

Without auxiliary winding

Excellent Line and Load Regulation

±3% LED Output Current Accuracy

Thermal Regulation Function

The WS3413 integrates a 550V power MOSFET. With

few external components, the LED output current can be

precisely controlled.

LED Short/Open Protection

Current Sensing Resistor Open Protection

Auto Fault Recovery

The WS3413 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 WS3413 has ultra low start up current and ultra low

operating current.

Available in DIP7/SOP8 Package

Applications



E27 LED Bulb, Spot Light

PAR30, PAR38 Lamp

T8/T10 LED String

Other LED Lighting

The WS3413 is available in DIP7/SOP8 Package.
