This design idea takes an unusual path to a power-handling DAC by merging an upside-down LM337 regulator with a simple (just one generic chip) PWM circuit to make a 20-V, 1-A current source...

Which step best approximates the digital signals you work with every day? The piecewise-linear step starts with a jerk, mindlessly follows a perfectly uniform ramp, and smacks hard into its upper limit. Real signals don’t do that...

The original application of the circuit was to locate coins, but it applies wherever you need to locate metal objects...

Vishay Intertechnology introduced two new IGBT and MOSFET drivers in the compact, high isolation stretched SO-6 package...

Toggle, slide, push-pull, push-push, tactile, rotary, etc. The list of available switch styles goes on and on...

Figure shows an example of on/off circuitry commonly used in battery-operated devices. The p-channel MOSFET, Q1, serves as a power switch...

Toshiba Electronics Europe introduces the TB67S559FTG 50 V/3.0 A stepper motor driver IC that supports constant current control with built-in current detection...

Figure silly-simple voltage-to-time ADC is an exercise in dynamic range. Assuming that it is used with a 10-MHz counter/timer, its resolution is roughly 10 µV per count for inputs around 0 V and 100 mV per count at 1 kV, and it never really over-ranges...

Short-circuit protection is an obvious requirement for a power supply, especially when its load connects to a cable that's subject to damage...

Whether its buck, boost, or buck/boost, internal or external switch, milliamps or tens of amps, a literal cornucopia of programmable output switching regulator/converter chips are commercially available...
