Power MOSFET tutorial, Part 1

Power MOSFETs are well known for superior switching speed, and they require very little gate drive power because of the insulated gate. In these respects, power MOSFETs approach the characteristics of ...

Semiconductor Back-to-Basics: Power MOSFETs

Power MOSFETs (Metal-Oxide Semiconductor Field Effect Transistors) are three-terminal silicon devices that function by applying a signal to the gate that controls current conduction between source and ...

Back to Basics: Voltage Regulators, Part 2

Two basic IC topologies are employed in dc power sources. If the output is lower than the input voltage, the IC is said to be a step-down, or buck converter. If the output is higher than the input ...
