Design files

Overview

This reference design showcases an interleaved boost converter controlled by LM5122-Q1, operating from a 9.0-V to 16.0-V input voltage range, generating an output voltage of 24.0 V with a maximum load current of 60.0 A (10.0 A per phase).

Features
  • High converter efficiency for minimal components temperature rise
  • Can be operated with the higher output power if a higher component temperature rises is acceptable
  • Low output voltage ripple (smaller than 1% peak-to-peak) for audio applications
  • Low input voltage ripple leads to better EMC
  • Modular design which enables easy modification for higher and lower output power by removing or adding phases
