Bidirectional DC/DC Converter Reference Design for 12-V/48-V Automotive Systems
TIDA-01168
Overview
The TIDA-01168 reference design 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.
Features
- 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
