Texas Instruments LM65680-Q1 | Demoboard LM65680-Q1EVM

Automotive 65V, 8A synchronous buck converter optimized for low-EMI

Overview

TopologyBuck Converter
Input voltage6-70 V
Output 15 V / 8 A
IC revisionA

Description

The LM65680-Q1 evaluation module (EVM) is a synchronous buck DC/DC regulator that employs synchronous rectification to achieve high conversion efficiency in a small footprint. The EVM operates over a wide input voltage range of 6V to 70V, which offers outsized voltage rating and operating margin to withstand supply-rail voltage transients while providing a regulated output of 5V. The output voltage has better than 1% setpoint accuracy and is adjusted by modifying the feedback resistor values, permitting the user to customize the output voltage as needed.

Features

  • Wide input voltage operating range of 6V to 70V
  • 5V output voltage with 1% setpoint accuracy
  • Rated for 8A of load current
  • Low minimum on time (40ns maximum)
  • Optional dual-random spread spectum and slew-rate control for EMI mitigation
  • Fully assembled and tested PCB layout with small footprint

Typical applications

  • Advanced Driver Assistance Systems (ADAS), Automotive infotainment and cluster, Hybrid, electric, and powertrain systems
