PMP7256, Power Management for C667x DSP AVS Core (CVDD)

PMP7256, This reference design aims to supply the AVS core supply(CVDD) in the Keystone Multicore DSPs, mainly the C66x series. The C66x series uses Smart Reflex technology to enable the DSP to control its supply voltage. In order to meet this requirement, this design combines a Synchronous Buck Converter (TPS56121) with the voltage Programmer for POL (LM10010). The LM10010 accepts a 6-bit VCNTL from the DSP and changes the output voltage of the TPS56121 to what the DSP requires
