4 Low-Side Diode

A footprint D2 is available for a Schottky diode to be placed in parallel with the low-side FET. This can improve efficiency because a discrete Schottky will have a lower forward voltage than the bodu diode of the low-side FET. The footprint fits SMA size devices. If desired, the low side FET can be removed entirely, and the LM2727 will run as an asynchronous buck controller.
