Mechanical switches can be noisy, generating multiple transient pulses that may cause faulty operation of fast digital circuits. In this design, a pair of MOSFETs are ...

The simple current-limiting load switch shown in Figure 1 will be familiar to most readers. In this circuit, a high level signal applied to the input switches on MOSFET Q2, which energizes the load.

The circuit of Figure 1 provides a "diode-OR" function for applications that must switch automatically between the main and backup supply voltages. Such applications include battery-backed memory ...

As electronics engineer I have a mental collection of circuits that I’ve gathered over the years, much like a mechanic collects specialized tools as they work. All engineers do this and the tools in ...

Mission critical servers and communications equipment must continue to operate, even as circuit boards and cards are plugged-in or pulled-out for maintenance and capacity adjustment. Hot swap ...

The choice between a flyback or single-ended primary inductance converter (SEPIC) topology often ends with the designer choosing the most familiar one, but that’s not always the right option, say John ...
