Hello,
The DM8148 EVM uses a TPS659113 for most of the supplies and a TPS5116 for the DDR. On the EVM there are eight DDR devices.
In our design we are sourcing all CVDD from a single output of the TPS659113 (VOUT) leaving VDD1 and VDD2 free. These outputs are capable of supplying up to 1500 mA. I would like to use these outputs to driver our DDR3 devices, of which there are four 16-bit devices configured for two banks of 32-bit. One output for VTT and the other for VDDQ.
Is this OK? Are there other factors that I should know that would recommend the use of the TPS5116 anyway?
Thanks
Michael
