Four-output synchronous buck reference design for automotive telematics control units
Description
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.
Features
- 12-V input: bus converter with selectable 3.3-V or 5-V outputsFour selectable load switch outputs with 3-A maximum loadAll switching converters operate above 2 MHz to avoid AM bandVery good output ripple with and without load (Built for easy testability using configurable jumpers and test points
