This processor supply reference design is an automotive power solution for use in highperformance, single-core-voltage application processors in advanced driver assistance systems (ADASs). This design can support core supply currents up to 10 A at 0.9 V. The design can also operate with a wide input voltage range, withstand reverse battery conditions, and support start-stop and cold-crank down to a 3.5-V input with an undisturbed output. The sub-AM band switching frequency of the power front end improves efficiency and reduces board temperatures when compared to a power front end with faster switching frequency. The multiphase configuration and integration of supplies enables lower electromagnetic interference (EMI) and higher efficiency. This reference design also provides results for conducted emissions tests for CISPR 25 Class 5.
A fully assembled board has been developed for testing and performance validation only, and is not available for sale.
