Bidirectional DC/DC converter reference design for automotive

The TIDA-01168 reference design from Texas Instruments is a four-phase, bidirectional DC-DC converter development platform for 12-V/48-V automotive systems. The system uses two LM5170-Q1 current controllers and a TMS320F28027F microcontroller (MCU) for the power stage control. 

LM5170-Q1 subsystems use average current feedback for current control whereas the C2000 microcontroller provides voltage feedback. Such a control scheme eliminates phase current balancing typical for multiphase converters. A system based on LM5170-Q1 allows a high level of integration, which reduces printed-circuit board (PCB) area, simplifies design, and speeds up development.


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