A4401 - Automotive Quasi-Resonant Flyback Controller

Description

This device provides all the necessary control functions to provide the power rails for driving a vacuum fluorescent display (VFD) using minimal external components.

The power supply is based on a quasi-resonant, discontinuous flyback converter, operating near the critical conduction boundary.

Features

  • Multiple output regulator.
  • 7 to 40 V input supply.
  • Low EMI conducted and radiated emissions.
  • Adaptive quasi-resonant turn on/off control.
  • Minimal number of external components.
  • Enable input which can be driven with respect to the battery voltage.
