Automotive Isolated 15V/4.5W Bias Power Supply Reference Design

PMP30227

Design files

Overview

This reference design displays a power supply solution to generate an isolated 15V rail with a maximum load current of 300mA from an input voltage between 8V and 28V. It also contains an optional Buck converter on the secondary side to provide a 5V rail with 200mA load current for a microcontroller.

Features
  • Built and tested
  • Isolated
  • Primary side regulation, no optocoupler
  • Good load regulation
