Hello,
I am using the LM5006 regulator. I am getting good performance, but I would like to try to lower the current drawn by the system when there is no load and the regulator is enabled and switching. My design is based largely on the minimum-ripple configuration from the eval board.
I can see that ~1mA is drawn by the feedback resistors, and this could probably be lowered to 500uA.
However, my main place to look is the inductor. I am currently using an 82uH inductor with 0.341mohm DCR. I do not think the DCR would effect no-load operation, but perhaps I could reduce current draw by using a larger inductor? I have seen that behavior before in other buck regulators, hopefully it could work for this one as well.
Any other recommendations are welcomed, of course!
Thanks,
Dave
