Description

This 400W ¼ brick DC/DC converter leverages the LM5119’s dual-phase capability to drive a 33A load in an industry-standard ¼ brick module footprint. This compact design delivers 97% peak efficiency while maintaining balanced current through each phase, which reduces thermal stress and enables lower system cost by eliminating the need to over-design the surrounding power components.

Features
  • Greater than 94% efficiency
  • Switching frequency 100 kHz
  • Input range 33V to 60V maximum
  • Output voltage of 12V at 33A
  • Standard ¼ brick footprint (2.3" x 1.45")
  • This end-equipment design is production-ready and supported with design files and an application note
