In recent electronic devices, the demand for energy savings has become increasingly difficult to meet due to very stringent requirements such as high efficiency, low power dissipation, and reduced ...

Applications ranging from consumer electronics to high-power energy-conversion systems leverage the benefits of dc-dc power converters in their designs. Among these, flyback converters are popular for ...

Available in 4W, 7W, and 13W ratings, the Coiltronics line of Power-over-Ethernet transformers are available for use with a wide variety of PWM controllers from several IC manufacturers, providing ...

The pulse-edge transformer (PET) is used as a medium to transmit PWM pulses from a secondary-side controller, such as EZ-PD™ PAGxS, to a primary-side controller, such as EZ-PD™ PAGxP, for AC/DC ...

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.

A common part used to create a high voltage is a CRT flyback transformer, having been a ubiquitous junk pile component. So many attempts to use them rely on brute force, with power transistors in ...

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 ...

Figure 1 shows the architecture of a conventional isolated flyback converter. These converters can be found frequently in power classes of up to about 60W. A supply voltage is converted to an output ...

What’s the optimal power-conversion design? To find out, different topologies for mobile-device adapters and chargers were evaluated, and adapter performance using two power semi types were compared.

As the demand for smaller form factors and higher energy efficiency for charger/adapter grows, the wide bandgap (WBG) device technology is gaining popularity. To use the potential of WBG and thus ...
