Overview

The LM5123EVM-BST evaluation module showcases the features and performance of the LM5123-Q1 wide input voltage synchronous boost controller. The standard configuration is designed to provide a regulated output of 24 V at 100 W, from an input voltage of 9 V to 18 V and switching at 440 kHz. The output voltage can be dynamically modified up to 45 V at 100 W using the TRK pin of the LM5123-Q1.

This EVM is designed for ease of configuration, enabling a user to evaluate many different applications on the same module. Functionality includes; low IQ operation, internal feedback resistors, bypass mode operation when VIN is greater than VOUT, dynamic output voltage tracking, power good (PGOOD) indicator, programmable frequency dithering, programmable under voltage lock out (UVLO), and over voltage protection.

Features
  • Input voltage range: 9 V to 18 V
  • Output voltage 24 V at 100 W
  • 440 kHz switching frequency
  • Dynamically configurable output voltage up to 45 V at 100 W
