TFS764HG

AC DC Converters, Offline Switchers Overview

The TFS764HG is a dual forward and flyback power controller from the HiperTFS series by Power Integrations. It integrates high-power dual-forward converter and medium-power flyback (standby) converter functions into a single eSIP power package. The device provides controllers for dual-forward and flyback converters, including high-side and low-side drivers, and a three-terminal high-voltage power MOSFET. This single-chip solution reduces the need for expensive external pulse transformers and simplifies layout, loading, and thermal management complexities associated with dual-forward designs.
