Fig 1. The buck converter schematic shows the voltage feedback loop and the fast peak CMC loop. The current waveform as seen by the shunt is the dominant signal at the ramp of the PWM comparator. Fig ...

The course is focused on current-mode control techniques, which are very frequently applied in practical realizations of switched-mode. Upon completion of the course, you will be able to understand, ...

For the PDF version of this article, click here. Over the years, power supply designers have been persuaded that current mode is superior to its voltage-mode counterpart. As a result, the major PWM ...

Modern power delivery systems with DSPs, FPGAs and CPUs run on lower supply voltages and consume higher current. In fact, sub-1 V voltages are everywhere now. Meanwhile, intermediate bus voltages have ...

Editor’s note: In Part one, we looked at an intro and the basics of linear regulator and switching power supply operation. This final part two will look at design considerations of the switching power ...

National Semiconductor has introduced its first 6V to 100V current-mode buck controller. The LM5116 is designed for step-down regulator applications from a high voltage or widely varying input supply.
