Overview

PMP20330 is an isolated Flybuck converter utilizing the LM5160 for industrial applications. This design has a minimum operating input voltage of 18V and a maximum input voltage of 31V. The design is capable of sourcing 1A continuous current at 3.3Vout, and 0.5A continuous current at 5Vout. Switching frequency is set to 200kHz. A Wurth transformer 750316561 is used for this design.

Features
  • 18V to 31Vin, 7.35V primary output, secondary outputs: +3.3V @ 1A, +5V @ 0.5A – IC capable of 4.5V to 65V input
  • Primary side regulation without opto, good regulation, within +/-5%
  • No loop compensation required/fast transient response
  • Low BOM count and cost, compact solution size
  • No RC snubber at primary winding
