    Options for reducing the MLCC count for DC/DC switching regulators

    Multilayer ceramic capacitors (MLCCs) are popular in electronic circuits, particularly for decoupling power supplies, but have become harder to procure due to a severe market shortage of MLCCs in larger case sizes, which began in 2018. Market indicat...

    Understanding the difference between capacitors, capacitance and capacitive drop power supplies

    Knowing the difference between a capacitor’s rated value and its actual capacitance is key to ensuring a reliable design. This is especially true when considering high-voltage capacitors used in capacitive drop power supplies for equipment like...

    How to avoid the pain of a discharged device

    Frustration caused by a dead mobile device battery is not limited to adults with phones. Children too young to read can transform from charming angels to noisy demons when their tablet battery dies. This can be especially painful when it occurs during a long car ride. I have seen this happen, and recommend taking all reasonable steps to avoid it...

    Layout matters: solving pinout assignment issues for DC/DC converters in WCSP packages

    The miniaturization trend in consumer electronics has taken hold for good. Consumers are demanding smaller electronics with better features: more flash capacity in solid-state drives, faster smartphones, more integrated communication modules, etc. To achieve this, engineers must look for increasingly power dense solutions. One challenge associated with...

    Do all rails need low Iq?

    All designers of ultra-low power systems are concerned about battery life. How much time will elapse before the battery in a fitness tracker will need recharging? Or, for primary cell systems, how long will it be before a technician must service the smart meter and change the battery? Clearly, the design goal is maximum battery runtime. For a fitness...

    Deciphering low Iq: Using WEBENCH® to design near 100% duty-cycle for ultra-low power applications

    Many battery-powered applications require a step-down buck converter to work in 100% duty-cycle, where V IN is close to V OUT , in order to extend battery run time when battery voltage is at its lowest value. For example, let’s say that there are two lithium manganese dioxide (Li-MnO 2 ) batteries powering a smart meter. Li-MnO 2 batteries are...

    Optimizing power density with eFuses

    Do you still remember what it was like have dial-up internet? If not, here’s an audio snippet that may jog your memory ! It was only a few years ago that you had to wait 10 minutes for someone to get off the phone before you could log in to your AOL Instant Messenger account, which probably took another five minutes with the typical 40-kbps transfer...

    How to reduce the size of your 13-W PoE PD solution

    You just got a big product out the door and are enjoying some well-deserved downtime when your product manager decides to swing by. Surprise, surprise: he wants the next-generation product to have more features and a smaller form factor. Luckily, you may be able to squeeze out some area from your Power over Ethernet (PoE) powered device (PD) solution...
