PMP7899

Design files

Overview

PMP7899 is an isolated flyback converter utilizing the LM5022 for industrial applications. This design has a minimum operating input voltage of 8V and a maximum input voltage of 18V. A custom flyback transformer from Coilcraft is used in this design.

Features
  • Isolated output for safety
  • High power density : 48W/5.6 Sq. inches
  • Small solution size
  • High step-up ratio
  • Excellent line and load regulation with opto-coupler
  • Cycle-by-Cycle current limit
