TEA1716T Overview
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...
TEA1716T Key Features
- Integrated PFC and HBC controllers
- Universal mains supply operation from 70 V to 276 V (AC)
- High level of integration resulting in a low external ponent count and a cost
- Integrated Burst mode sensing
- pliant with Energy Using Product Directive (EuP) lot 6
- Enable input to enable only the PFC or both the PFC and HBC controllers
- On-chip high-voltage start-up source
- Stand-alone operation or IC supplied from external DC source
- Boundary mode operation with on-time control
- Valley/zero-voltage switching for minimum switching losses
