Even robotic systems occasionally need a cooling fan. When they do, the cooling circuit must be an intelligent one that makes minimal demands on power consumption and space. The circuit described here ...

[Les] from [Les’ Lab] has designed a driver for laser diodes up to 10 watts, and decided to show us how it operates, tells us what we should keep in mind when designing such a driver, and talks about ...

A generally accepted fact about relays and solenoids is that after they’re driven into the actuated state, only half as much coil voltage and therefore only one fourth as much coil power, are required ...

Several years ago, Paul Rako, in collaboration with the late, great Bob Pease, wrote a terrific article about the finer theoretical and practical points of electromagnetic solenoid-driver circuits. 1 ...

This application note is intended for engineers designing an isolated AC-DC LED driver using the LinkSwitch-PH family of devices. It provides guidelines to enable an engineer to quickly select key ...

Nixie tubes can add some retro flair to any project, but they can also complicate your electronics quite a bit: after all, you need to generate a voltage high enough to ignite the tube and then switch ...
