Overview

The LM51772EVM-HP demonstrates a flexible high-power buck-boost design using the LM51772 wide-VIN buck-boost controller. The evaluation module is configured to operate with an input voltage range from 9V to 48V and provides a regulated 20V output with up to 5A of load current.

Features
  • Input voltage range: 9V to 36V
  • Output voltage 20V (20V default, adjustable 3V to 48V) with up to 5A (240W)
  • High efficiency, synchronous buck-boost conversion
  • Easy access to configuration features
  • Flexible design using standard MOSFETs
