Designing a Power Tree for an Automotive SoC (Download)
Sept. 26, 2022
Advanced driver-assistance systems (ADAS) and infotainment systems-on-chip (SoCs) continue to ramp up the computing power, leading to higher power demands. An SoC can require more than 10 different power rails, with currents ranging from hundreds of amperes to a few milliamperes. Crafting an optimal power tree for these applications isn’t a trivial task. Here, we’ll discuss how to design an optimal power architecture for an automotive SoC, with a focus on the pre-regulator design.
