Figure shows the architecture of a conventional isolated flyback converter. These converters can be found frequently in power classes of up to about 60 W...
The high temperature of the power components is a known phenomenon in electronics. To overcome this challenge, the designers mount heatsinks on the components to dissipate the heat...
I2C is a popular bidirectional serial communications bus having a clock and a data line. Both line’s drivers consist of an open drain ground-referenced N-channel MOSFET with a pullup resistor connected to a supply...
The circuit is a single-supply version of a programmable Schmitt trigger, or a comparator with hysteresis...
In this article, I introduced an AC/DC flyback switching power supply that converts 85 V-260 VAC to 5 VDC-2.5 A, which can be used in various applications...
Modern measurement systems often operate with single 5-V power supplies, yet their input signals may have large common-mode voltages that exceed the supply by tens or hundreds of volts...
Using a blue LED can pose problems when available power-supply voltages don't meet or exceed the LED's 3 V forward-voltage drop. This Design Idea shows how to drive a blue LED from a 3 V battery...
In the automotive industry, in which the goal is to produce cars with simpler, lighter wiring looms, any interface that uses just one wire instead of two offers a distinct advantage...
Anemometers are an important category of environmental sensor. Articles about their design, data capture, and linearization have comprised topics featured in EDN Design Ideas, several quite recently. Less well covered, however, has been the topic of accurate, inexpensive, (even improvisational) methods for their testing and calibration...
