    Shrink module size with Flip Chip On Lead (FCOL) package technology

    Power modules are becoming increasingly popular in many market segments – the ability to buy a power supply that already includes the switching inductor is a big advantage. The main reasons engineers are choosing power modules as opposed to a discrete alternative are: Reduced Solution Size. Power Modules are typically smaller than what designers...

    How to achieve higher system robustness in DC drives, part 1: negative voltage

    I recently moved to a new apartment, so I decided to go shopping for a vacuum cleaner. As I walked around the appliances section, I noticed how many of the vacuums were cordless. The manufacturers also seemed to be advertising more suction power, lon...

    In automotive lighting, it’s time to say goodbye to discrete solutions

    Auto manufacturers are using light-emitting diodes (LEDs) beyond the traditional front, rear, day-running, stop and turn lights to make their vehicles stand out in the market. LEDs are now appearing in side markers, license plates, brand logos, welco...

    How to charge and discharge battery test equipment

    A battery test system (BTS) offers high voltage and current control accuracy to charge and discharge a battery. It is mainly used in manufacturing during production of the battery. Battery test equipment can also be used in R&D departments to study battery performance. One typical application of a BTS is to charge and discharge a one-cell lithium...

    How to select a MOSFET - Hot Swap

    Over the course of this series of blogs , I have covered a number of different FET applications, from motor control to power supply. Alas, I have arrived at the final topic – selecting a MOSFET for hot swap. When a power supply is abruptly disconnected from its load, large current swings across the circuit’s parasitic inductive elements...

    Why are there so many control modes for step-down DC/DC converters and controllers?

    One of the questions I receive frequently is why there are so many control modes for step-down DC/DC converters and controllers. Whether hysteretic, voltage mode, current mode, constant on time or D-CAP™ mode control (and all of their derivatives), it seems a new one comes out just as we’ve gotten comfortable with the last one. A few...

    Create a cost-effective boost power supply with true load-disconnect functionality

    The fast-growing consumer electronics market brings opportunities as well as challenges for boost converters. The huge volume drives the market to be very cost-sensitive, so you will need to make trade-offs between solution cost and performance. The need for true load-disconnect functionality A boost converter does not have a native mechanism...

    Accurately measure vital signs with low Iq and a small form factor

    These days, it feels like the “portable future” is right around the corner. Devices that used to be cumbersome and bulky have become light and portable. I saw this firsthand in personal electronics: cellphones were once heavy and slow; they’re now slim, fast and have an increasingly longer battery life. I’ve also witnessed...
