DC/DC converter system

Block diagram

Overview

Our integrated circuits and reference designs help you create DC/DC converter designs that efficiently transfer energy to and from one power rail to another in systems ranging from 12 V to 800 V.

Design requirements

DC/DC converter systems require:

  • High performance and fast digital control loops enabling highly efficient power conversion and increased power density.
  • Simplified and efficient integration of bidirectional 12-V to 48-V DC/DC converter solutions.
  • Load balancing for parallel operating (multi-phase) power supplies.
