Beschreibung

The TIDA-01168 reference design is a four-phase,bidirectional DC-DC converter development platformfor 12-V/48-V automotive systems. The system usestwo LM5170-Q1 current controllers and a C2000™TMS320F28027F microcontroller (MCU) for the powerstage control. LM5170-Q1 subsystems provide currentcontrol using an innovative average current controlscheme whereas the C2000™ microcontroller providesvoltage feedback to the system. Such a controlscheme eliminates an additional phase-currentbalancingcircuitry, which is typical for multiphaseconverters. A system based on LM5170-Q1 allows ahigh level of integration, which reduces printed-circuitboard (PCB) area, simplifies design, and speeds updevelopment. The TIDA-01168 reference design fulfillsthe typical operating voltage requirements for12-V/48-V automotive systems.
