Nonisolated DC/DC step-down voltage conversion is almost exclusively based on the ubiquitous buck regulator topology. The multiphase buck regulator has inherent advantages over its single-phase ...

Buck converters are a critical element in modern power management, providing efficient voltage step‐down in a wide range of systems from battery-operated devices to industrial applications. Their ...

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 ...

The first thing I ever built without a kit was a 5 V regulated power supply using the old LM309K. That’s a classic linear regulator like a 7805. While they are simple, they waste a lot of energy as ...

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 ...

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 ...

For the PDF version of this article, click here. For several years, the dc-dc converters used to power microprocessor core supplies in PCs have been fed by a 12-V source. This voltage was chosen to ...

Buck-boost converters produce a regulated output voltage either less than or greater than the input voltage. When the input voltage is higher than the output, the converter acts as a buck. When the ...

Diodes has announced four automotive buck converters for 48V rail point-of-load use. The parts are similar, but rated at 5 to 100V or 5 to 80Vin, and 2.5A or 3.5A out. There are not synchronous ...
