An autotransformer is a transformer having part of its winding included in both the input and output circuit. A simple autotransformer connection is shown in Fig. 1. Note that because there is a ...

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 ...

Serial Peripheral Interface (SPI) output driver chips are popular with embedded designers because they provide multiple outputs without using any CPU I/O pins. This article explains how to adapt a ...

Some applications require a positive voltage to be generated from a negative input voltage. This can be done either by using a transformer based topology, such as a flyback converter, or with a ...
