WebA high-side p-channel MOSFET and a low-side n-channel MOSFET tied with common drains (Figure 5) make a superb high-current ªCMOS equivalentº switch. One fault common to such circuits has been the excessive crossover current during switching that may occur if the gate drive allows both MOSFETs to be on simultaneously. N-Channel P-Channel ±15 ... WebThe term “synchronous” is used to describe the process of turning “on” the low-side MOSFET when the high-side MOSFET is turned “off” (and visa versa). This results in higher efficiencies than those obtained by the classical non-synchronous converter that utilizes a Schottky diode in place of the low-side MOSFET.
