    Improve circuit breaker leakage current response with a voltage supervisor

    A residual current detector (RCD) or residual current circuit breaker (RCCB), detects leakage currents when an alternate path to ground is established. RCDs isolate the power source from the leakage path by tripping open the circuit. Unlike fuses, th...

    Big things for power come in small packages

    Semiconductor packaging includes much more than just the material encapsulating the chip. While containing critical connections to the chip itself and to the circuit board, packaging technologies also include many innovations that help deliver the pe...

    Improving data-center efficiency with eFuses

    According to Forbes, global data centers used approximately 416TW (4.16 × 1014W) of electricity in 2017, with U.S. data centers contributing about 90 billion kilowatt hours to that number. With artificial intelligence making strides and 5G arou...

    How to use a voltage reference as a voltage regulator

    A version of this post was also published on Electronic Design . Have you ever needed to bias a low-current load and simply didn’t want to add another voltage regulator? Or been in a situation where you need a reasonable level of voltage accurac...

    Using an RGBW LED driver to elevate LED human-machine interface designs

    Products are becoming very intelligent and connected with each other. Devices such as speakers , TVs, refrigerators, set-top boxes and smoke detectors are no longer objects that just sit there – users can control them remotely or through voice ...

    QFN soldering tips and tricks

    If you’re looking to power a space-constrained, high-power-density, thermally critical application, high-efficiency converters in tiny quad flat no-lead (QFN) packages offer great performance value. But you might ask yourself, when you test and...

    How to add hysteresis to a DC/DC converter

    Is enable hysteresis not included in the DC/DC converter you are designing with? Or is the built-in enable hysteresis too small? Modern DC/DC converters use an enable pin to control the design conditions at which the power supply turns on and off. It...

    20 million reasons to use GaN

    It was a cold and snowy day in Toronto. We were brainstorming in the basement of the local university’s advanced power electronics research lab. Ironically, the conversation was focused on heat – not actually generating it for warmth, but how to reduce it in our power converters. We had pushed MOSFETs and IGBTs to their respective limits...
