Bidirectional DC-DC converter reference design for 12V/48V automotive systems

10-10-2018 | Texas Instruments | Automotive & Transport

The TIDA-01168 reference design, from Texas Instruments, is a four-phase, bidirectional DC-DC converter development platform for 12V/48V automotive systems. The system uses two LM5170-Q1 current controllers and a TMS320F28027F 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 enables a high level of integration, which reduces the PCB area, simplifies design and speeds up development.
