![]() With a control switch, the MOSFET is on, the voltage across the inductor is V in minus V out. More on the pros and cons of schottky, PN diodes, and MOSFETs later on in this seminar. It could also be a PN diode for voltages above 200 volts, where schottky usually arent available. ![]() Ive drawn the control switch, or High Side Switch as an internal MOSFET, because thats the most common type of controlled switch used in modern switching regulators. Up until now, the switches were represented as ideal devices. ![]() And then topologies that are derived from the three basic switchers.Īnd talk in general terms about the elements of a switching converter that can now be found inside the package of the control IC.Īs well as those components that still live outside the package.
