In a synchronous, buck switching power supply, the two FETS and the output inductor meet at the phase node (Figure 1). The phase node often connects directly to the control IC. The voltage on this ...

The final part of this series will start with bias servo circuits for automatic set up. The FETs pinch off or threshold voltage can vary widely for the same part number. Depending on the fabrication ...

Over the recent weeks here at Hackaday, we’ve been taking a look at the humble transistor. In a series whose impetus came from a friend musing upon his students arriving with highly developed ...

Reverse polarity is one of the most common causes of circuit failure, from hobby projects to industrial systems. The good news is that a well-designed reverse polarity protection using MOSFET ...

Local power that is available for protection circuits, such as desaturation detection. Among the disadvantages of this type of driver are the cost, complexity and board space required for all the ...

A Metal-Oxide-Semiconductor Field-Effect Transistor (MOSFET) is a fundamental building block of modern electronics. It is a field-effect transistor (FET) where the voltage applied to a terminal (gate) ...
