Automotive Power Design for Front Camera Systems Using Single-Core Voltage Application Processors


Design files


This reference design provides a broadly-applicable automotive power design for a variety of ADAS processors, focusing on front and rear camera applications. The design supports an input range of 4 V to 48 V to supply common processor power rails through discrete components.  This adds to the versatility of the design while providing an optimized layout to help you achieve automotive compliance for EMI/EMC regulatory requirements associated with producing an automotive electronic subsystem.



  • Power design for a wide array of ADAS processors
  • Designed for wide-Vin and cold-crank conditions
  • Size-optimized design (83.0 mm x 57.0 mm)
  • Supports peripheral power supply needs such as CMOS sensor, inputs and outputs (I/Os), memory, and secondary microcontroller (MCU)
  • Uses an input filter for improved EMI and EMC performance
