WebFor the switch MOSFET shown in Figure 6, a lower gate charge (Q G) in Equation 5 enables lower power loss and a faster switching time; however, this contributes to more parasitic turn-on of the rectifier MOSFET. A happy medium can be obtained in the design to accommodate these trade-offs. P GATE G TOT G SW= × ×Q V f ( ) (5) WebWhen the input voltage pulse is low, the MOSFET is OFF and the current Io keeps the clamping diode ON. After the input voltage transitions high (to +10 V or so), the MOSFET gate–source and gate–drain capacitors charge as the MOSFET gate voltage rises. The …
Webhighest efficiency, but also low gate charge for ultra-fast switching in high frequency applications. As the breakdown voltage increases, the device undertakes more stress in a different dimension. While the voltage rating goes up, the current rating often goes down. This is the consequence of power limiting and is
Webhigher input voltage require a lower QG (gate charge) to cut down the switching losses in the switch MOSFET (Q1). For a rectifier MOSFET (Q2), low R DS(on) is most important, but don’t ignore the gate power.
