This reference design uses an LM63635-Q1 synchronous buck converter to output either a 3.3-V or 5-V rail. The bus converter switches at 2.1 MHz, and the load converters (TPS62810-Q1) switch at 2.2 MHz. The system is designed for telematics control unit power. Easily configurable jumpers allow users to enable and disable the bus converter, load converters and load switches for up to 3-A maximum load at each output.
