App Note: Non-isolated 360mA buck DC/DC converter

Saturday, November 19th, 2011

This buck converter design uses the LinkSwitch-TN IC to output DC directly from rectified mains outlet.  It converts mains high voltage to smaller DC voltages suitable for electronics devices, and has the ability to output up to 360mA of current. It's based on the standard buck topology, except that the...
