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 ...

Linear constantcurrent drivers, for instance, offer low EMI, low cost, and use only a few components. Many designers favor them for low-current applications where power loss is a minor concern. If ...

Sunnyvale, Calif.—Advanced Analogic Technologies Inc. (AnalogicTech) announced two charge pump products that are aimed at helping designers build smaller, more feature-rich mobile handsets. The ...

Display Driver Integrated Circuits (DDICs) serve as a critical nexus between image processing units and visual display devices, including LCDs, OLEDs and other emerging panel technologies. These ...

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 ...
