High Efficiency Synchronous Buck Converter, 12V Input to 1.1V at 25A using the TPS51117 (PMP2993)

PMP2993 uses the TPS51117 in a synchronous buck converter to generate 1.1V at 25A from a 12V input. The design was originally used in a notebook application which had a 3 cell lithium ion battery for the input. The TPS51117 has a light load efficiency mode to keep the no load losses low in portable applications.
