    Understanding valley current limit

    The concept of current limit seems pretty straightforward: when you increase the output current of a DC/DC converter, at a certain point it’s not possible to increase it any further. This level is the current limit, which naturally leads to the idea that the current is limited at some particular peak or maximum level. With this in mind, the...

    The new PoE standard: It’s almost here

    This July will mark six years since the beginning of the journey for IEEE 802.3bt, the IEEE standards project that will standardize 4-pair Power over Ethernet (PoE). I began preparing for the standard when I attended my first IEEE standards meeting ...

    How to achieve higher system robustness in DC drives, part 2: interlock and deadtime

    While commuting to work, waiting for a traffic light I noticed the green and red light sequence that prevents traffic flow conflicts, or crashes. The crossing traffic directions are out of sequence to ensure safe driving. Also the yellow gives a little extra time to ensure everything runs smoothly. In a half bridge power train, such as in DC drives...

    Why you need a programmable lighting engine when designing LED driver circuit

    Advanced light-emitting diode (LED) animation effects like “deep breathing” and “color chasing” are becoming increasingly popular. However, a common issue designers’ face is that the microcontroller (MCU) is overloaded b...

    Boosting efficiency for your solar inverter designs

    With summer upon us here in the U.S., I’m already thinking about beach days and poolside BBQs. Growing up in South Florida and currently living in Texas, I’m very familiar with hot and sunny days. Similarly, I’ve gotten used to rece...

    Optimizing solar power with battery chargers

    As solar-powered devices become more portable and interconnected, rechargeable batteries eliminate the need for AC adapter input power and take advantage of the abundant energy from the sun. For example, devices such as e-bikes and Internet Protocol network cameras spend most of their time outside and away from power outlets, making solar charging...

    Effects of IC package on EMI performance

    he origin of electromagnetic interference (EMI) in switched-mode power supplies can be traced back to the transient voltages (dv/dt) and currents (di/dt) generated during the switching of power metal-oxide semiconductor field-effect transistor (MOSFE...

    How to modify a step-down converter to the inverting buck-boost topology

    When looking for a DC/DC converter to create a negative voltage, in many cases you will use a step-down converter in the inverting buck-boost topology. While dedicated inverter devices such as the very-low-noise TPS63710 are easier to design wi...

    How to approach a power-supply design – part 5

    In this final installment of the topology blog series, I’ll introduce the inverting buck-boost converter and Ćuk converter. Both topologies allow you to generate a negative output voltage from a positive input voltage. Inverting buck-boost converters The inverting buck-boost topology can step up and step down its input voltage while the...
