Beschreibung

The 25A LFPAK demonstration board is a single phase buck converter design to demonstrate the performance of NXP LFPAK MOSFETS in a small form factor point of load (POL) circuit. The very small 3.3 cm x 6.1 cm (1.3x2.4 inch), four layer board converts 12V nominal input to 1.2 V nominal output and is capable of output currents of 25 amps while maintaining case temperatures at or below 90 C with a minimal 200 LFM airflow at 25 C ambient. Efficiencies above 90% are achieved (12v in, 3.3v out), on this small demonstration board due to the superior level of on-resistance and thermal performance of the small S08 foot print NXP LFPAK devices.
