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 ...

An increasing number of appliances draw a very small current from the power supply. If you need to design a mains powered device, you could generally choose between a linear and a switch-mode power ...

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 ...

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 ...

Power supply manufacturers sometimes hear from customers with unfortunate dilemmas, such as, “I need to operate the power supply outside its rated voltage range.” Or, “What happens if I exceed my ...

Standard cells libraries are usually designed to operate at a specific value of supply voltage referred to as “nominal voltage”. This article details the performance trade-offs in terms of power ...

If you work on simple digital projects, just about any bench supply will offer the voltage and current you’re looking for.
