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 ...

High-efficiency step-down switching regulators for positive voltages are very common, however negative step-down switching regulators (negative voltage in, negative voltage out, common ground) are not ...

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 ...

I have wanted to make a pulse generator for years. I know you can buy perfectly good ones, but not if you want non-overlapping outputs to drive the mosfets in synchronous-rectified dc-dc converters.
