Editor’s note: This article is based upon a 2006 EDN article by Jim Williams; see Reference 1. There are six different types of FETs, but of the two major categories of FETs, enhancement mode devices ...

Improving the efficiency of a power-supply design can yield many rewards. In a server farm, better efficiency translates into smaller size, reduced cooling costs, and a lower electricity bill. In a ...

Acopian Technical Company has introduced the Low Profile 2 series of switching regulated power supplies designed for use in ...

The switching power supply inFigure 1 produces 3.3V dc froman input voltage of 2.5 to 20V dc withhigh efficiency. The circuit operates atan input voltage as low as 1.5V once itstarts from a minimum of ...

Power-supply designers frequently encounter projects where the input voltages are much higher compared to the low output voltages usually require to power the target equipment. Typical output needs ...

Today, 80% of all input/output (I/O) devices in automation applications are supplied with 24VDC power. The second most popular voltage is 120VAC, which is used on 15% of all I/Os. Over the past decade ...

If you work on simple digital projects, just about any bench supply will offer the voltage and current you’re looking for. However, if you’re working with valves, you’ll often ...

You may have seen the Ruideng range of programmable power supply modules from China: small and relatively inexpensive switch-mode buck converters, with microprocessor control and a front panel ...

Bear Power Supplies has begun shipping a 10W medical power unit designed to meet tighter safety requirements on leakage ...
