Description

This reference design details a power management circuit which is capable to accurately regulate the output voltage at the end of a cable without using sense connections. The implementation is based on a completely integrated step down converter circuit enabling a small total solution while still capable of handling up to 3 A at the output.

Features
  • 1% accurate load regulation without sense connections
  • small solution
  • more than 10W output power possible
  • simple design, small BOM
  • automotive qualified components
