Basic Calculation of a Buck Converter's Power Stage (Rev. B)
www.ti.comnecessary to stabilize the input voltage due to the peak current requirement of a switching power supply. The best practice is to use low-equivalent series resistance (ESR) ceramic capacitors. The dielectric material must be X5R or better. Otherwise, the capacitor loses much of its capacitance due to dc bias or temperature.

Power MOSFET - Vishay Intertechnology
www.vishay.comThird 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 TO-247 package is preferred for commercial-industrial applications where higher power levels preclude the use of TO-220 devices. The TO-247 is similar but superior ...
Power MOSFET Basics - Understanding Voltage Ratings
www.mouser.comswitching (UIS). The standard UIS circuit and simplified waveforms are shown in Figures 2a and 2b. Though overvoltage and avalanche breakdown are evident, it should be noted that the UIS is a current-driven, transient event. The avalanche current in this case is the same as the peak inductor current indicated by the red dashed line in Figure 1b.
