Beschreibung

This reference design demonstrates how the required power rails for the VE2302 device can be powered by TI's regulator ICs. AMD’s Minimum Rails power consolidation of supplies. See AMD’s Power Design Manager (PDM) tool, for all available power consolidation options. Use PDM when estimating power for any application. This reference design uses example power estimations. The design can also be used as a foundation for designing the power tree for other devices of the AI Edge series. The original power source for this system is typically between 8VIN to 18VIN and capable of delivering about 50W of power.

Eigenschaften

  • An optional front-end protection (FEP) sub-circuit,controlled by the LM74910-Q1 integrated circuit(IC), that acts as a programmable electronic safetyswitch with numerous safety features.
  • A LM25148-Q1 buck converter, referred to as the 5V pre-regulator, that accepts the wide input voltage, and generates a well-regulated 5V voltage level. This 5V rail, in turn, supplies the main point-of-load (POL) converters, which regulate the various voltages needed to supply the VE2302 device.
  • Two TPS62876-Q1 regulator ICs are used to implement a dual-phase, interleaved converter that powers the main digital core rail.
  • A LP87694-Q1 Power Management IC (PMIC) and TPS746-Q1 Low Dropout (LDO) linear regulator are used for the remaining rails.

Typische Anwendungen

  • Short and medium range radar - 76 to 81GHz with RFCMOS, Radar ECU, Mechanically scanning LIDAR, Long range radar - 76 to 81GHz with RFCMOS
