Hi,
I find a reference design for C667X in TI'WEB,http://www.ti.com/tool/tidep0011?keyMatch=C667X%20CVDD&tisearch=Search-EN-Everything. This reference design aims to supply the AVS core supply (CVDD) in the Keystone Multicore DSPs, mainly the C66x series. The C66x series uses SmartReflex 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 (LM10011).
In C6657 EVM, it use UCD9222+UCD7242 to apply CVDD. So, may I use this solution(TPS56121+LM10011) for TMS320C6657 with its CVDD?
Best Regards
Guan
