PMP7208, 5V In 33W Univ 4-Bit VID I/F AVS power Supply for TCI6636K2H/6638K2H

PMP7208, 5V In 33W Univ 4-Bit VID I/F AVS power Supply for TCI6636K2H/6638K2H. This reference design aims to supply the AVS core supply for Kepler DSPs like the C6638. 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 the TPS40303 Synchronous PWM Buck Controller with external CSD16325Q5 NexFETs and a low-cost, four-transistor circuit to generate the required VID for the Core Supply AVS requirement. This solutions enables a universal 4-bi VID power supply for processors that need AVS implementation through 4-bit VID programming
