LTC3623 – Switching regulator doubles as Class-D audio amplifier

Leave a Comment / Electronics News Updates /

Sure thing, Elektor has published several designs of adjustable power supplies based on switching regulators, so we know that doing this properly in a reproducible way and without making things overly complex requires some serious head scratching. The anxiety may be reduced vastly though by a new adjustable synchronous buck regulator which uses a single

Reverse engineering a server CPU voltage regulator module

Leave a Comment / Electronics News Updates /

A recent ebay fishing expedition yielded an interesting little part for the very reasonable sum of about five pounds. It’s a voltage regulator module from a Dell PowerEdge 6650 Xeon server. I originally bought this because I had the idea of salvaging parts from it to use in another project. These are high quality modules

Use an LM317 as 0 to 3V adjustable regulator

Leave a Comment / Electronics News Updates /

Most engineers know that they can use an inexpensive, three-terminal adjustable regulator, such as Fairchild Semiconductor’s LM317, as an adjustable regulator to only some necessary value of voltage, such as 36 or 3V. This value cannot be less than 1.25V without employing other approaches, however. The devices’ inner reference voltage is 1.25V, and their output
