Overview

The LM5177EVM-HP demonstrates a flexible high power buck-boost design using the LM5177 wide-vin buck-boost controller. The evaluation module is configured to operate from input voltage range of 4.2 V to 36 V and provide a regulated 16-V output with up to 9.4 A of load current.

Features
  • 4.2 V to 36 V input voltage range
  • 16 V with up to 9.4 A (150 W) output voltage 
  • High efficiency synchronous buck-boost conversion
  • Easy access to configuration features
  • Flexible design using standard 5 mm x 6 mm FETs
AC/DC & DC/DC controllers (external FET)
