This reference design provides the system rails for automotive vehicle-to-everything power. A 5-V bus is generated by the off-battery buck converter (LM63625-Q1), and this supplies all the point-of-load devices. The bus converter switches at 2.1 MHz, and the load converters (TPS628501-Q1) switch at 2.2 MHz. Easily configurable jumpers allow users to enable and disable each device on the board and toggle the bus converter operational modes. A front-end EMI filter is included.
Features
- Small solution size measuring 1.20 inches X 1.06 inches
- All converters operate with an output voltage ripple of less than 2% at full load
- All switching converters operate above 2 MHz to avoid the AM band
- Built for easy testability using configurable jumpers and test points
- Automotive-qualified solution
