全電壓內含MOSFET高效率T8燈管/E27球泡燈方案

G5361

AC/DC 8W-20W High PF and High Efficiency LED Controller

Non-isolation Buck LED Lighting Driver with Active PFC

 

General Description

The G5361 is a high performance AC/DC non-isolation buck PWM controller for LED lighting applications. The device has a fully integrated active PFC circuit with Quasi-Resonant mode to achieve high power factor values, high efficiency and low total harmonic distortion. It is also equipped with 500V power MOS internally to minimum external components counts and PCB size.

The G5361 provides rich protection functions, which include wide range Under Voltage Lockout (UVLO) at 20Von and 7Voff , Over Current Protection (OCP), Output LED String Open Protection, Output LED String Short Protection, VCC Over Voltage Protection (OVP).

The high level of functional integration minimizes the external component count giving major advantages in terms of cost and circuit board area. The device is supplied in a SOP8 package.
