This article discusses the low current input circuit ideas using the 6N139 series optocouplers. A few of the circuit designs are signal detection, transient detection, matrices and non-loading line ...

Without careful design, it is easy to dissipate as much energy in the conversion circuit as gets delivered to the load. The dc/dc conversion method of choice for moderate power output is often a ...

This article presents some circuit ideas using the RCD driver. Such ideas are voltage-dimming control, potentiometer dimmer, PWM to analogue dimming control, and RGBW mixer. 0 – 4.5 V Dimming Control ...

A hot-surface warning light is a safety device, so it must operate reliably whenever the surface is hot. Heat, however, complicates the light’s power source, because high-temperature power wiring is ...

Use of buck-boost circuits in switching-regulator ICs. Considerations in level-shift circuit design. Switching regulators with internal level shifting. The magnitude of the negative voltage generated ...
