UCC28951QPWRQ1 is an automotive AEC-Q100 Grade 1 phase-shifted full-bridge controller for isolated high-power DC/DC converters requiring adaptive ZVS timing and synchronous-rectifier control.

Best for

  • Automotive isolated DC/DC converters
  • Phase-shifted full-bridge power stages
  • Converters using synchronous rectification
  • High-voltage ZVS power conversion

Avoid if

  • A non-isolated low-power regulator is required
  • Direct high-current MOSFET gate drive without external drivers is required
  • A topology other than phase-shifted full bridge is planned

Check before use

  • Confirm UCC28951-Q1 timing behavior is suitable for the selected power stage
  • Tune adaptive delay and synchronous-rectifier timing on hardware
  • Validate current-limit filtering and leading-edge noise immunity
  • Confirm thermal and automotive qualification requirements for the full assembly
