Description

The PMP6680 non-isolated DC/DC reference design uses the TPS40170 with a 43V-53V input and a 12V output to deliver up to 20A. The design achieves around 97% peak efficiency at 12A while using surface mount power MOSFETs and ceramic output capacitors. The TPS40170 is a 4.5V to 60V input full featured synchronous buck controller and is available in a 3.5mm x 4.5mm 20-pin QFN package.
