Switch-mode regulators include the buck (step-down) and the boost (step-up), forward and flyback topologies, as well as the SEPIC, hysteretic and multiphase converters. Two basic IC topologies are ...

Many design teams are focused on increasing the switching frequency of their buck converters to improve ripple characteristics and performance The challenges facing designers of PWM controllers go far ...

Pulse-width modulation (PWM) is an efficient method for controlling the light intensity of a lamp or the speed of a simple DC motor. It lets you take advantage of the load's inertia by switching the ...

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 ...
