SSL4120 Datasheet | NXP Semiconductors

Resonant power supply controller IC with PFC for LED lighting Rev. 2.1 - 18 February 2014 Product data sheet 1. General description The SSL4120 integrates a Power Factor Corrector (PFC) controller and a controller for a Half-Bridge resonant Converter (HBC) in a multi-chip IC. It provides the drive function for the discrete MOSFET in an up-converter and for the two discrete power MOSFETs in a resonant half-bridge configuration. Efficient PFC operation is achieved by implementing functions for Quasi-Resonant (QR) operation at high-power levels and QR with valley skipping at lower power levels. OverCurrent Protection (OCP), OverVoltage Protection (OVP) and demagnetization sensing...
