    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...

    Protector, monitor or gauge – selecting the correct battery electronics for your Li-ion-powered system

    Lithium-ion batteries have high energy density and a long cycle life; they also lack the memory effect of other technologies. Such characteristics make them attractive for portable electronic systems. But lithium-ion batteries also need to operate wi...

    Choosing the right SOA for your design: discrete FETs vs. power blocks

    In power semiconductors, design engineers use the safe operating area (SOA) to determine whether it’s possible to safely operate a device such as a power metal-oxide semiconductor field-effect transistor (MOSFET), a diode or an insulated-gate bipolar transistor (IGBT) at current and voltage conditions in their application without causing damage...
