It has a nice combination of input and output range, and the size is insane: about 1/4" square. It will do forced synchronous, burst, or synchronized switching.
I wonder if it can be persuaded to convert a positive rail to two negative outputs. Sadly, LT Spice does not yet include a model for this one. My designs often need a few negative supplies, and negative switchers a neglected area.
I'd love to xray one of these. I can't imagine how they crammed the inductors inside.
