General Description

The RT7220D is a Synchronous Rectifier (SR) controller for Flyback converters operating in Continuous Conduction Mode (CCM), Discontinuous Conduction Mode (DCM) and Quasi-Resonant (QR) mode.

The RT7220D will sense the drain voltage of MOSFET to determine SR gate on/off so as to minimize turn-off dead-time and enhance efficiency.

The RT7220D supports the wide output voltage range from 3V to 21V, and a HV LDO is especially built-in for the MOSFET gate driver at low output voltage.

Key Features

  • Suitable for Flyback Converter in CCM, DCM, and Quasi-Resonant (QR) Mode.
  • Suitable for 3V to 21V VOUT Range.
  • ZVS Function to Optimize Efficiency (Work with the Primary-Side Controller RT7757).
