Asynchronous vs. synchronous topologies. How a synchronous boost LED controller minimizes efficiency losses. The challenge of low-input-voltage operation. High-power LEDs continue to proliferate in ...

Any boost-converter design will have a practical limit to how much it can step up a voltage from input to output. Pulse-width modulation (PWM) controllers have timing limits that restrict the minimum ...

Dc/dc converters have evolved from simple three-terminal regulator circuits into complex electronic subassemblies that are critical in the power distribution systems of many applications. Good ...

Find a downloadable version of this story in pdf format at the end of the story. Efficiency and density (Watts/Volume) have long been the metrics used to compare the performance of isolated DC-DC ...
