66AK2Gx DSP + ARM Processor Power Solution Reference Design


Design files


This reference design is  based on the 66AK2Gx multicore System-on-Chip (SoC) processor and companion TPS65911 power management integrated circuit (PMIC) which includes power supplies and power sequencing for the 66AK2Gx processor in a single device. This power solution design also includes the first stage buck converters to support a 12 V input and the DDR termination regulator for DDR3L memory. The reference design is tested and includes hardware reference (EVM), software (Processor SDK) and test data.

  • TPS54620 and TPS54429 first stage buck converters
  • TPS65911 companion PMIC supporting power sequencing and power supplies as required by K2G
  • Integrated real time clock (RTC) for time-critical applications via the TPS65911
  • LP2996A DDR3L termination regulator
