FSFR2100 Datasheet Power Switch

Manufacturer: Fairchild (now onsemi)

Overview: FSFR-Series — Fairchild Power Switch (FPS™) for Half-Bridge Resonant Converter May 2008 FSFR-Series — Fairchild Power Switch (FPS™) for Half-Bridge Resonant.

This datasheet includes multiple variants, all published together in a single manufacturer document.

General Description

The FSFR-series are a highly integrated power switches designed for high-efficiency half-bridge resonant converters.

Offering everything necessary to build a reliable and robust resonant converter, the FSFR-series simplifies designs and improves productivity, while improving performance.

The FSFR-series combines power MOSFETs with fast-recovery type body diodes, a high-side gate-drive circuit, an accurate current controlled oscillator, frequency limit circuit, soft-start, and built-in protection functions.

Key Features

  • Variable Frequency Control with 50% Duty Cycle for Half-bridge Resonant Converter Topology.
  • High Efficiency through Zero Voltage Switching (ZVS).
  • Internal SuperFET™s with Fast-Recovery Type Body Diode (trr=120ns) for FSFR2100 and UniFETs with Fast-Recovery Type Body Diode (trr.
