Overview
SSL4120 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 ensure safe operation under all conditions The HBC module is a high-voltage controller for a zero-voltage switching LLC resonant converter.
It contains a high-voltage level shift circuit and several protection circuits including OCP, open-loop protection, capacitive mode protection and a general purpo...
