This proof-of-concept details the design considerations of the discrete power design for the AC8025 (from AutoChips™) system-on-chip (SoC) power rails with a power-management IC (PMIC) design. The design uses the TPS6593-Q1 PMIC, TPS62875-Q1 synchronous buck converters, and TPS745-Q1 low-dropout (LDO) regulators. The original power source is the battery. The battery voltage is converted to regulate the 5V or 3.8V bus. The LM25149-Q1 converts the battery voltage to regulate the bus voltage. All components in this design are automotive-qualified.
A fully assembled board has been developed for testing and performance validation only, and is not available for sale.
