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 ...

Advanced Analogic Technologies Incorporated has announced today two new high-performance charge pump products which enable designers to build dramatically smaller, more feature-rich mobile handsets.

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 ...

Ordering a PCB with mistakes sucks. We should help each other avoid such mistakes – especially newcomers. One of the best ways to avoid these mistakes, especially if it’s your first one, is to get a ...

All circuits, analog or digital, have characteristics dependent on the values of their component parts. Invariably, these parts are non-ideal in many ways. Even their most fundamental characteristics, ...
