Rajkumar Sharma electronics-lab.com This module is a non-isolated 7 A DC-DC converter. The module can convert any DC voltage between 7 V to 50 V to a 5 V DC with load current up to 7 A (Figure 1). The project has been designed around LM5116 Wide ...

Emmanuel Odunlade electronics-lab.com One of the best things about being a maker is the ability to make your own tools. We have covered the development of several electronics tools in past, from voltmeters to battery testers. For today’s ...

Davinder Oberoi EDN A common circuit in electronics is the square-wave, astable multivibrator (one-shot), which is useful for various purposes, such as timing circuits and audible alarms. The most common way to generate the desired square wave is ...

Marián Štofka EDN The circuit in Figure 1 is an alternative to a high-side current monitor in a recent Design Idea (Reference 1). That monitor uses the Analog Devices AD8212 and an external high-voltage bipolar PNP transistor. The ...

by Shyam Tiwari EDN The need for a compact telemetry system poses a challenge for designing a small, light, low-component-count system. Interfacing serial data from the microprocessor is also difficult because most low-cost RF transmitters do not ...

Mirko Pavleski Arduino.cc A simple to build, but very sensitive electromagnetic field detector. This is a simple device capable of detecting very weak electromagnetic fields (Figure 1). The relative field intensity is displayed on the LCD display ...

Chau Tran and Paul Mullins, Analog Devices EDN You sometimes need to measure load currents as large as 5 A in the presence of a common-mode voltage as high as 500 V. To do so, you can use Analog Devices’ AD8212 high-voltage current-shunt ...

Rajkumar Sharma Electronics-lab.com This project is based on STK984-090A from ON Semiconductor which is a fully-integrated inverter with current rating 20 A and supply voltage 40 V DC (Figure 1). It has been designed to drive the Brushless DC ...

Jeff Magee It is emphasised that this should not be used for medical purposes. Displays your pulse rate, blood oxygen level and a moving graph of each heart beat, the photoplethysmogram (PPG). About this project This project implemented on an ...

by Yuchen Yang and William Xiong Design Note Introduction In traditional isolated high voltage flyback converters, tight regulation is achieved using optocouplers to transfer regulation information from the secondary-side reference circuitry to the ...
