Tool/software:
What is the polarity of the SD shutdown signal? The documentation says that when the SD signal is grounded the converter is on. This makes sense. However, section 6.5 in the March 2016 datasheet says the part is in shutdown mode when SD is below 0.8v. The old National Semiconductor LM2665 datasheet from 2005 says the opposite.
So which is it?
