Design files

Overview

The PMP10735 reference design is a 5V, 3A output power supply in a 2-layer board design for off-battery automotive instrument cluster applications. The reference board has an input EMI filter and optmized layout for improved EMI performance.

Features
  • LM43603-Q1 automotive grade SIMPLE SWITCHER® wide Vin synchronous buck regulator
  • 6.5V to 35V input voltage range
  • 94% peak efficiency at 12V input
  • EMI optimized 2-layout design in compliance with CISPR 25 Class 5 conducted emissions standard
  • 400kHz frequency PWM , and PFM at light load
  • Reference board is tested, and the test report and design files are included
