Web10 jul. 2024 · To calculate the power dissipated by a resistor, you need to know two of the following quantities: The resistance R R; The electric current I I; or The voltage drop V V. There are two possible formulas for power dissipation. The first one requires you to know resistance and current: P = R\cdot I^2 P = R ⋅ I 2 WebThe efficiency is added to the duty cycle calculation, because the converter also has to deliver the energy dissipated. This calculation gives a more realistic duty cycle than just the formula without the efficiency factor. Use either an estimated factor, e.g., 90% (which is not unrealistic for a buck converter worst-case
