    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

    The 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 (MOSF...

    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...

    Look at the details when designing an industrial PC – 1% is not always 1%

    With process geometries of semiconductor technology declining to 10nm or below, designing the power supply for an industrial PC or single-board computer gets challenging like never before. In addition, the Industrial Internet of Things (IIoT) and Industry 4.0 are creating a stronger push toward smaller computing systems with increased performance. Figure...

    How to design a simple constant-current/constant-power/constant-voltage-regulating buck converter

    Introduction In a previous blog titled “ How to design a simple constant current/constant voltage buck converter ,” I discussed how to design a constant current/constant voltage converter (CC/CV). With the addition of a simple modification, the functionality can be modified to regulate the output power and operate within a constant power...
