Manufacturer: onsemi

Overview: Advanced Pulse Frequency Modulation (PFM) Controller for Half-Bridge Resonant.

General Description

The FAN7631 is a pulse−frequency modulation controller for high−efficiency half−bridge resonant converters that includes a high−side gate drive circuit, an accurate current−controlled oscillator, and various protection functions.

The FAN7631

Key Features

  • include variable dead time, operating frequency up to 600 kHz, protections such as LUVLO, and a selectable latch or A/R protection using the LS pin for user convenience. The Zero.
  • Voltage.
  • Switching (ZVS) technique reduces the switching losses and improves the efficiency significantly. ZVS also reduces the switching noise noticeably, which allows a small Electromagnetic Interference (EMI) filter. Offering everything necessary to build a reliable and robust resonant converter, the F.
