Power Supply Reference Design for Automotive Microcontroller in Gateway and Body Control Module

TIDA-01412

Design files

Overview

This discrete power supply reference design demonstrates performance of the Freescale™ MPC5748G microcontroller. This reference design uses five DC/DC converters, it offers a more flexible and scalable design than when using a PMIC. It supports numerous automotive applications such as gateway and central body-control modules.

Features
  • Supports 2.7-V to 16-V, 32-V peak input voltage
  • Flexibility in terms of load and scalability to future generations of the microcontroller
  • < 1% accuracy on the LV core supply of the MCU
  • Requires five DC/DCs for simple power

A fully assembled board has been developed for testing and performance validation only, and is not available for sale.
