In the last installment of Circuit VR, we walked around a simplified buck converter. The main simplification was using a constant PWM signal. The result is that the output voltage is a fixed fracti… ...

Even though buck converters, and other DC converters like boost and the mysterious buck-boost converter, seem like magic even to us, there is some interesting electrical theory going on if you ...

Synchronous buck converters have received great attention in low power, low voltage DC-DC converter applications in recent years due to their high efficiency. International Rectifier Inc. has ...

Though stepdown converters (buck converters) are extremely popular, the rules of thumb and calculations thatspeed their design can be hard to find. Donald Schelle and Jorge Castorena, Technical ...

As electronics become more advanced, the need for efficient power management increases. One crucial element of power management is the DC-DC converter, which is a device that converts DC voltage from ...

Also, the converter's efficiency dropped from 85.4% to 83.1% due to an additional 234 mW of losses in the input capacitor's ESR. When a single 22-μF ceramic capacitor is used, but moved 0.5 in. (1.2 ...

Download this article in PDF format. 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 ...

Buck converters, or step down converters, put out less power than they receive, and the tracking signals in the output can get stuck. This results in a small but harmful frequency fluctuation, or ...

STMicroelectronics is has chosen an isolated buck converter topology for a 10W dc-dc converter that provides a regulated local primary power rail, plus a moderately regulated isolated secondary power ...
