1-12-2001 | Despite the fact that fuses have had almost exclusive reign during much of the previous century, the impact made by resetable fuses such as...

1-12-2001 | Only simple materials and a little bit of skill are needed to build an RS232 switch. All that you need are two 9-way sub-D plugs with solder...

1-12-2001 | A Polyswitch is an electronic fuse, which interrupts a protected circuit when the nominal current has been exceeded, but returns to its orig...

1-12-2001 | There are very many switching regulator ICs for reducing a dc voltage. In the ‘step-down’ operating mode, an internal switch connects the in...

1-12-2001 | This circuit shows one way to generate both positive and negative output voltages using a step-down switching regulator. The Micrel (www.mic...

1-12-2001 | Normally, two pushbuttons are needed to control a thyristor, namely — you guessed it — one to switch it on and one to switch it off. With th...

1-11-2001 | In designing a product that is powered from the mains, there are various factors that ultimately determine the choice of power supply. Incre...

1-07-2001 | This circuit has been designed to respond only to two hand claps which occur in (relatively) quick succession, and to ignore one hand clap o...

1-07-2001 | One of the most frequent uses of n-channel MOSFET’s is as a voltage controlled switch. To ensure that the MOSFET delivers the full supply vo...

1-07-2001 | There are presently many switching regulator ICs. However, the STA801 and STA802 provide two switching regulators in a single package, each...
