This reference design is focused on the power tree for an automotive infotainment display unit covering various power supply rails including two off-battery converters providing 5.0-V and 3.3-V, and intermediary system rails of 1.8-V and 1.1-V. The test results demonstrate high efficiency, low heat dissipation and CISPR 25 class 5-conducted emissions compliance.
