High side buck converter

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. WebThe synchronous buck converter is used to step a voltage down from a higher voltage to a lower voltage. Synchronous buck converters are very popular in industry today and provide high efficiency solutions for a wide range of applications.
