Microprocessors and application-specific integrated circuits (ASICs) require low-voltage, high-current power supplies. These supplies usually have very strict requirements on output-voltage deviations ...

Second-stage output filters are often used to attenuate the output voltage ripple of a switching power supply. They can also isolate one load circuit from another. In this power tip, I will describe ...

For the PDF version of this article, click here. Many electronic circuits can rapidly shift between a sleep state and full load operation, placing a heavy requirement on the power converter to ...

The power transistor must be chosen to provide fast response while also withstanding high power dissipation. Several electrical and thermal characteristics must be considered: 1. An array of N current ...
