WebSep 16, 2024 · Thank you for your patronage. Why does the high-side switch turn ON with the Buck converter in the figure below? Since the threshold value of the high side switch is 0.5 V, to turn on the high side switch, for example, VG = 10 + 1 V is required as shown below. However, in the simulation circuit, the high side switch is turned on with VG = 1 V. WebDec 19, 2024 · If you make a buck converter that converts 12V to 1V to power a CPU, its duty cycle will be very low so the diode would conduct 92% of the time, plus the diode's forward voltage is 60% of the output voltage, which means the diode losses will be about 50% of output power. So replacing the diode with a FET really increases efficiency. john a grigley
