Product Introduction

Overview

The NXP SSL4120T/1,518 is a high-efficiency, single-chip resonant controller designed for high-power LED applications. It integrates controllers for power factor correction (PFC) and a half-bridge resonant converter (HBC) in a single chip, making it an elegant and cost-effective solution for designing LED drivers and power supplies. This controller is particularly suited for commercial, industrial, and street lighting applications, both indoors and outdoors, where demand for high-power LED solutions is growing rapidly.
