Description

The PMP4419 is a fully tested multi-rail AC/DC power supply reference design for industrial applications like Programmable Logic Controllers (PLC).  The input range is 90Vac to 264Vac, and the DC outputs are 24V/1A and +/-15V/0.6A respecitivley with excellent cross-regulation (<5%).  The QR flyback controller LM5023 is selected for the application and achieved 85% @ 230V full load.  The design measures 118mm x 71mm x 20mm and has been thermally characterized.

Features
  • 24V/1A, +/-15V/0.6A triple outputs
  • QR flyback controller with high efficiency (85%)
  • Good thermal performance with low component count
  • Good output regulation & cross regulation (below 5%)
  • Protection features OCP and OVP
  • Low profile: 118mm x 71mm x 20mm
