Design files

Overview

PMP8917 has been designed as a competitive open-frame alternative for the communications market with 36-72Vin to 5V/2A. The product is supplied in the industry standard footprint of 2.0 x 1.0 x 0.394 inches. PMP8917 has a basic insulation system from input to output making it suitable for a wide variety of applications. LM5020 is used as synchronous Flyback converter controller for PMP8917 with 92.9% converter efficiency.
