An adjustable load provides a constant-current load for testing power supplies and batteries. It allows you to set the load current to up to 1.05 A, using a potentiometer, and displays the current on a three-digit LED display controlled by an ATtiny84...

Renesas Electronics introduced the RA6W1 dual-band Wi-Fi 6 wireless microcontroller, along with the RA6W2 MCU that integrates both Wi-Fi 6 and Bluetooth Low Energy (LE) technologies...

Alright, I admit that the title is a bit over the top. So, what do I mean by it? I mean that: The application of PWM control to a regulator does not significantly degrade the inherent DC accuracy of its output voltage...

I’ve recently published Design Ideas showing circuits for linear PWM programming of standard bucking-type regulators in applications requiring an output span that can swing below the regulator’s sense voltage...

Without a doubt, FM transmitter and receiver are among the top favorite electronic project topics, however, building a digital FM transmitter can be a challenging project for electronics enthusiasts...

There’s been interest recently here in the land of Design Ideas in a family of simple interface circuits for pulse width modulation control of generic voltage regulators...

The circuit converts the input DC voltage into a pulse train. The period of the pulses is proportional to the input voltage with a 50% duty cycle and a nonlinearity error of 0.01%...

Many recent Design Ideas have involved button-pushing to control power. Some may have been more resistant to contact-bounce than others – but how can we really check that?...

Implementing a simple digital-to-analog converter by cascading a single pulse width modulator and an analog low-pass filter is nothing new. Nor is applying to a filter the sum of the outputs...

Lightning is one of nature’s most intense and unpredictable forces, but thankfully, we have got technology to help us stay ahead of the storm...
