It has long been known that the simple combination of a depletion-mode MOSFET (and before these were available, a JFET) and a resistor made a simple, serviceable current source such as that seen on ...

It isn’t unusual to expect a precisely regulated voltage in an electronic project, but what about times when you need a precise current? Over on EDN, prolific [Stephen Woodward] explains how ...

We have been looking at the history of some HVDC devices such as the mercury-arc valve and the thyristor valve for the past few months. The mercury-arc valve made HVDC transmission possible (1950s), ...

[Afroman] contacted us to share his new video on the LM317. The humble LM317 adjustable voltage regulator is everywhere. From wifi routers, to high spec lab equipment. Given a noisy input and a ...

A power supply’s source, in actual use, is never ideal. The real behaviour, including parasitics, needs to be considered to build a reliable power system. When we use power supplies, we ensure that a ...

Linear Technology Corporation announces the LT8705, a very high efficiency (up to 98%) synchronous buck-boost DC/DC controller that operates from input voltages above, below or equal to the regulated ...

While simple voltage converters can generate a fixed output voltage from an input voltage, this behavior isn’t sufficient in certain applications. An example is the control of a voltage node that has ...

Reference current and voltage source is used to supply any analog blocks. It is based on the reference voltage source forming temperature compensation ...

A well-organised industrial network operates efficiently within every control panel. At the system's core is an AC-to-DC ...

In this article we introduce a new class of DC-to-DC converters, an example of which is the LTC3336. It only consumes about 65nA of current in standby mode, making it ideal for battery-operated ...
