Splet02. maj 2016 · The conduction losses depend on the load current. With heavier loads, the conduction loss in the MOSFET increases and is the dominating factor. Conduction losses plus switching, driver and internal low-dropout regulator (LDO) losses lead to a considerable generation of heat and increase the junction temperature of the integrated circuit (IC). Splettors in a buck converter: conduction losses, switching losses, and static (quiescent) losses. MOSFETs have a finite switching time, therefore, switching losses come from the dynamic voltages and currents the MOSFETs must handle during the time it takes to turn on or off. Switching losses in the inductor come from the core and core losses. high peak buses 185 timetable high peak buses address
