Description

The PMP10834RevA reference design is a compact and thermally efficient design intended to step down a wide range of AC inputs (85VAC to 265VAC). This non-isolated Flybuck design incorporates the UCC28C42 PWM with an optocoupler feedback to provide 1% output voltage regulation. All the circuit components (including magnetics) are standard parts.

Features
  • Non-isolated AC-DC 5V/1A Flybuck converter.
  • Less than 45 degree C temperature rise on all parts.
  • 1% output voltage regulation accuracy.
  • Utilize all standard components (including magnetics).
  • Compact board size with 1.4" W x 2.7" L.
  • Test report available.
