Layout Considerations for Non-Isolated DC-DC Converters


要約: DC-DC converters are an excellent source of electric fields and magnetic fields. Their EMI spectrum begins at the switching frequency and often extends over 100MHz. To minimize capacitive couplings and magnetic couplings care must be exercised in printed circuit board (PCB) layout. Parasitic capacitance and parasitic inductance of the circuit must be evaluated so that the proper trade-off can be made early in the design phase.
