The FCH47N60F is Fairchild Semiconductor first generation of high voltage super-junction (SJ) MOSFET family that is utilizing charge balance technology for outstanding low on-resistance and lower gate charge performance.
The IRFP064N is a 60V 70A Third generation Power MOSFETs from Vishay provide the designer with the best combination of fast switching, ruggedized device design, low on-resistance and cost-effectiveness
The LTC3780 is a DC-DC-Auto-Up & Down-Voltage-Regulator-5-32V-to-1-24V-DC-Adjustable-Converter. My interest in this DC-DC switcher is to operate 19VDC laptops/notebooks and LCD TVs from 12V batteries/solar.
