This talk will show how to power an ADAS system needing > 100 W at 3.3V or 5V to power high current processors used to assist driving. 3.3V or 5V is especially suited for powering the point of load core voltage converters. Available power can be the traditional “12V” car battery (really 6-36V) or “24V” truck battery or a “48V” bus available in many electric vehicles EVs. A design approach covering all these input ranges, with a focus on overall power in the 200-300 W range will be presented. Design challenge areas such as covering wide Vin range, efficiency, thermal and dynamic load response, and their solutions will be presented. Available easy-to-use design tools will be shown.
