FSFA2100 - Fairchild Power Switch (FPS) for Half-Bridge PWM Converters

General Description

The growing demand for higher power density and low profile in power converter designs has forced designers to increase switching frequencies.

Operation at higher frequencies considerably reduces the size of passive components, such as transformers and filters.

Key Features

  • Optimized for Complementary Driven Half-Bridge Soft-Switching Converters.
  • Can be Applied to Various Topologies: Asymmetric PWM Half-Bridge Converters, Asymmetric PWM Flyback Converters, Asymmetric PWM Forward Converters, Active Clamp Flyback Converters.
  • High Efficiency through Zero-Voltage-Switching (ZVS).
  • Internal SuperFET™s with Fast-Recovery Type Body Diode (trr=120 ns).
  • Fixed Dead Time (200 ns) Optimized for MOSFETs.
  • Up to 300 kHz Operating Frequency.
  • Inte.
