Product data sheet
1. General description
The TEA1716T 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 operation 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 purpose latche.
