Overview

The LM68645-Q1 evaluation module (EVM) helps designers evaluate the operation and performance of the LM68645 family of wide input voltage buck converters. The LM68645EVM is configured to deliver a 5V output to a load requiring 4.5A or less. The LM68645EVM can be used in many different configurations by substituting other versions of the LM686x5 and re-configuring the board components.

Features
  • •3V to 65V wide input voltage range
  • 5V, 3.3V, and adjustable output voltage options
  • Up to 4.5A output current
  • 300kHz to 2.2MHz switching frequency
  • Minimized switch node ringing to reduce electromagnetic interference (EMI)
  • Input transient capability up to 70V
AC/DC & DC/DC converters (integrated FET)
