Part Number:TPS54672
I would like to use TPS54672 to sink continuously changing current at a certain voltage so that it can act as active load. I wanted to test before I go further and design the circuit. I got the EVM and build my circuit on breadboard. Before I power it up I want to make sure the following part I found the EVM user guide.
" To sink current, increase the current capacity of the 2.5-V supply, and connect a load resistor between the positive load terminal and the positive terminal of the 2.5-V supply. "
I do not really get why I need to put that load resistor first. If I need such load resistor what should be value? Is it really supposed to be connected between VTTQ and VDDQ pins?
Thanks for response in advance...
