Description

This reference design aims to supply the AVS core supply for Kepler DSPs like the C6638. The C66x series uses SmartReflex 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.

 

Features
  • AVS Capability- dynamically adjust Vo through low-cost 4-bit discrete transistor circuit
  • <3% DC tolerance over full load, including LM10010 tolerance
  • 4.5V to 6V Input Voltage
  • 1V output at 25A  nominal current, 30A peak
  • 300KHz switching frequency
  • 89%  efficiency at 5V input, 1Vout at 25A
