Abstract The QFN3333 demonstration board is a single-phase buck converter
design for demonstrating the performance of NXP Semiconductors’
QFN3333 MOSFETS in a small form factor Point-Of-Load (POL) circuit.
The 3.3 cm 6.1 cm (1.3 inch 2.4 inch) four layer board converts 12 V
nominal input to 1.2 V nominal output and is capable of a 25 A output
current while maintaining a case temperature at or below 90 C with a
