: Reduces switching losses in the MOSFET, leading to higher system efficiency.

: Compact residential and commercial luminaires.

Over-Voltage Protection (OVP) and Under-Voltage Lockout (UVLO). Output short-circuit and open-circuit protection. Supplies IC operating current during normal operation

High precision current control for LED longevity.

High voltage from the rectified line charges a VCC capacitor through a startup resistor.

The is a high-performance, isolated LED driver controller IC designed for offline AC-DC LED lighting applications. It is typically utilized in non-dimmable or dimmable LED bulb and tube light designs. The chip operates in Boundary Conduction Mode (BCM) or Critical Conduction Mode (CrM) , offering a cost-effective solution for low-to-medium power LED drivers.
