In 5 V power supplies, the MOSFET can be installed without filters. Directly adapters are selected control type. Some modifications use a damper. In this case, the conductivity parameter does not exceed 5.5 microns. Sensitivity, in turn, depends on the type of capacitors. For 5 V units, they are often used as an integral type.

In order to increase the current conductivity, pulse capacitors are used. However, it is important to note that they consume a lot of electricity. Pulse-type capacitors also provide additional load on the converter. To solve the presented problem, a triode is installed next to the transistor. It is more expedient to use a grid-type triode. Also on the market are modifications with an inverter.
