Overview

This reference design consists of three separable boards optimized for low EMI.

The three boards are labeled

  • PMP30930 Part A (using LM63635-Q1, PW package)
  • PMP30930 Part B (using LM63635-Q1, DR package)
  • PMP30930 Part C (Using LM61460-Q1)

Features
  • EMI- and safety-optimized layout using two ceramic input capacitors in series
  • Part C was tested with 400-kHz and 2.1-MHz switching frequency
