TEA1716T - Resonant power supply controller

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.

Features

  • 2.1 General features.
  • Integrated PFC and HBC controllers.

TEA1716T Resonant power supply control IC with PFC Rev. 3 — 30 November 2012 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.
