PMP10117

Design files

Overview

This reference design delivers 5.1V with 9A output current out of 48V. It could be also used for 48V automotive bus voltage.

Features
  • Suitable for telecom
  • Small footprint (power stage: 24mm X 44mm)
  • Added input filter to attenuate reflected ripple
  • Excellent load regulation
