For those living before the invention of the transistor, the modern world must appear almost magical. Computers are everywhere now and are much more reliable, but there are other less obvious changes ...

This application note explains the calculation of external capacitor value for buck converter IC circuit. Change of capacitance value due to temperature can obtain stable temperature characteristic by ...

DC to DC conversion has come a long way. What was once took an electromechanical vibrator and transformer has been reduced to a PC board the size of a largish postage stamp that can be had for a ...

In this article, we discuss the basic operation and design of a Fly-Buck™ converter. This discussion also includes a detailed explanation about the control and regulation of this converter. The ...

The synchronous buck converter is a widely used topology in low-voltage, high-current applications. One common application is a point-of-load (POL) converter that transforms a system bus voltage of 48 ...

Step-down (buck) voltage regulators have long been the preferred DC-DC conversion electronic workhorse thanks to their inherently high efficiency. Only in buck mode the current is directed to the ...

Basics of an isolated buck converter. Key specifications to consider in transformer selection. Steps involved in choosing the right transformer. Energy is transmitted to secondary coil only in T OFF ...

Analogue Devices has combined switched capacitor and inductive buck conversion in the same topology to reduce the size of step-down dc-dc converters. Called LTC7821, this is “industry first hybrid ...
