TEA1713T - NXP Semiconductors

TEA1713T Resonant power supply controller

The TEA1713 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. The efficient operation of the PFC is achieved by implementin.

Features

2.1 General features „ Integrated PFC and HBC controllers „ Universal mains supply operation (70 V to 276 V (AC)) „ High level of integration resulting in a low external component count and a cost effective design „ Enable input (enable only PFC or both PFC and HBC controllers) „ On-chip high-voltage start-up source „ Stand-alone operation or IC supplied from external DC source 2.2 PFC controller features „ „ „ „ „ Boundary mode operation with on-time control Valley/zero voltage switching for minimum switching losses Frequency limiting to reduce switching losses Accurate boost voltage regulat.
