Texas Instruments LM5141 | Demoboard PMP20682

Synchronous Buck Converter for Automotive Cluster Reference Design

Overview

TopologyBuck Converter
Input voltage5-40 V
Output 13.3 V / 10 A
IC revisionB

Description

PMP20682 is a synchronous buck converter reference design utilizing the LM5141-Q1 synchronous buck controller I.C. The design accepts an input voltage of 5V to 40V and provides a 3.3V output capable of supplying 10A of current to the load. An EMI filter is incorporated on the input. Optional frequency dithering and slew rate control are available for additional EMI control. Mounting holes are provided for a bottom-side MOSFET heat sink.

Features

  • Peak current-mode control
  • Selectable frequency dithering
  • Input EMI filter
  • Wide input voltage range
  • Selectable diode emulation or forced PWM

Typical applications

  • Hybrid Cluster with Active Graphics Support / Hybrid Cluster with Informational Graphics Support
