The LM5127EVM-FLEX showcases the features and performance of the LM5127-Q1 when configured with channel 1 as a pre-boost, and channel 2 and channel 3 configured as independent buck controllers. The input voltage range is 3V to 42V. The pre-boost can operate down to 3V during input transients, providing an output voltage of 6.9V. Channel 2, configured as a buck, produces 5V and up to 5A. Channel 2 is designed to provide a regulated 5V at up to 5A. Channel 3 is designed to to provide a regulated 3.3V at up to 7A.

  • Input voltage range: 3V to 42V
  • One pre-boost controller
  • Two buck controllers (5V at 5A), (3.3V at 7A)
  • Hiccup mode short circuit protection
