This reference design is an automotive front-end power solution for use in high performance cluster applications. This design supports three output voltage rails of 5 V, 3.3 V and 1.2 V. The design also operates with a wide input voltage range and withstands reverse battery conditions. A transient voltage suppressor at the input adds protection for load dump. The above-AM band switching frequencies and dithering reduce the burden of emissions compliance. This reference design also provides results for conducted emissions tests for CISPR 25 Class 5.
