A good switching power supply requires a good printed circuit board. In order to make an efficient one, the PCB designer should understand the phenomenon behind the operation of the typical switching ...

MOSFET selection for DC-to-DC switching controllers can be a complicated process. It is not sufficient to merely look at the voltage and current ratings for a MOSFET. A balance between low gate charge ...

This file type includes high resolution graphics and schematics when applicable. Switching power supplies are inevitable in today’s designs. They’re power-efficient and thermal-efficient, with various ...

With the increasing use of start-stop vehicle technology (which automatically turns off the engine while it is idling), more and more automotive systems must operate at low input voltages. These low ...

Here, Rich Miron, Applications Engineer at Digi-Key Electronics explores the operation of switch mode power supplies and explores make Vs. buy decision process for power supplies. Miron also ...

The most common type of power supply today is the switching supply. These units use pulse-width modulation (PWM) to regulate output. Supplies today employ several different PWM circuit configurations.

On paper, electricity behaves in easy-to-understand, predictable ways. That’s mostly because the wires on the page have zero resistance and the switching times are actually zero, whereas in real life ...

GarrettCom, Inc. has extended the capabilities of its 6-port Magnum ES42 Edge Switches and ESD42 Dual-homing Edge Switches and PES42P Power-over-Ethernet Edge Switches with a line up of IPS42 ...

A system that converts AC current from the wall outlet into the DC currents required by electronic circuits. A computer power supply converts AC into multiple DC voltages. For example, 12 volts is ...
