The rapid growth of automotive infotainment subsystems has created stringent performance requirements for power supply ICs in automotive applications. Depending on where the power supplies operate on the automotive power bus, they may be subjected to load-dump, jump-start and cold-crank conditions, as well as high ambient temperatures. The authors stress that selecting the optimal device to manage power on the bus is a vital design requirement.
