Texas Instruments

Texas Instruments

This design is a four-phase, bidirectional DC-DC converter development platform for 12-V/48-V automotive systems. It features a high level of integration, which reduces printed-circuit board (PCB) area, simplifies design, and speeds up development.


  • 12V input voltage range: 6V to 18V
  • 48V input voltage range: 24V to 54V
  • Reverse polarity, overcurrent overvoltage and overtemperature protection
  • Multiphase scalable option
  • Highly integrated solution using automotive qualified components
