Microcontrollers

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...

“Two halves make a whole” is a very old and often true maxim. For example, it’s almost always true when said about AC phase angle power control...

There is a new product type in the industry, the digital low dropout linear regulator. It offers telemetry and adjustability of a linear power supply in a very small footprint...

Integrating ADCs that provide accurate results without requiring a precision integrator capacitor has been around for a long time. A venerable example is that multimeter favorite, the dual-slope ADC...

I recently published a Design Idea showing some very simple circuits for PWM programming of standard regulator chips, both linear and switching, “Revisited: Three discretes suffice to interface PWM to switching regulators”...

Renesas Electronics Corporation introduced the RA2L2 microcontroller group with ultra-low power consumption and the industry’s first support for the new UCB-C Revision 2.4 standard...

Semiconductor laser diodes are often packaged with a photodiode. The output current from this photodiode can be monitored to regulate the output power intensity of the laser diode...

Many voltage regulator chips, both linear and switching, use the same basic two-resistor network for output voltage programming...
