MOSFET switches, whose rapid turn-on/turn-off capability and low on-resistance (R DS (on)) make them useful for power switching circuits, remains the dominant transistor type.

The MOSFET switch makes up one of the major sources of efficiency loss in a switch mode power supply circuit. Often times, as in the synchronous boost there are both high and low side switches.

Adding a high-side MOSFET switch to the conventional forward and flyback power converter design brings many benefits, especially in higher input-voltage applications. With the resulting two-switch ...

ROHM has responded to this requirement with the development of an ultra-compact low ON-resistance MOSFET that’s been ...

Metal-oxide semiconductor field-effect transistors (MOSFETs) see common use in applications ranging from the very small (like CPU transistors) to very large (power) switching applications. Although… ...

VRM is an essential part of every computer, but it's often given little attention. In fact, even many computer-savvy enthusiasts don't even know what it is or how it works. VRM stands for Voltage ...

Mechanical switches can be noisy, generating multiple transient pulses that may cause faulty operation of fast digital circuits. In this design, a pair of MOSFETs are used in ...

Mosfet opto-relays switch more than ever Omron has announced mosfet opto-relays that can switch 3.3Aac or 6.6Adc, giving them the highest-ever current carrying capacity, said the firm. Mosfet relays ...

Evaluating the magnitude of parasitic resonances and electromagnetic interference in a switch-mode power supply.

Using a MOSFET as a switch is generally pretty simple. Make the gate voltage sufficient with respect to the source and current flows through the channel. However, if you are switching higher ...
