Description

This discrete power supply reference design demonstrates a complete power solution for the Freescale™ MPC5748G Microcontroller. This simple discrete solution uses just five DC/DC converters, it offers a more flexible, scalable and cost-effective solution than when using a PMIC. This TI Design 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 Just five DC/DCs for a Cost-Effective and Simple Power Solution
