Controlling the brightness of LEDs requires a driver that provides a constant, regulated current. To achieve this goal, the driver topology must be able to generate a large enough output voltage to ...

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 ...

Diodes Incorporated has introduced a pair of synchronous DC/DC buck converters for use in applications such as monitors, TVs and STBs. The AP65500 and AP65400 deliver continuous load currents of 5 A ...

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 ...

Buck converters, a pivotal class of DC–DC converters, are widely implemented in modern power electronics to achieve efficient voltage step-down conversion. Recent advancements focus on enhancing ...

A 12V, 10A, 10MHz series-capacitor buck converter from Texas Instruments is said to have a current density of more than 50A/cm3, four times more than any other 12 V power management component or ...

Maxim Integrated has introduced the Max77827, a buck-boost converter featuring a quiescent current (IQ) of 6µA and peak efficiency of 96%. It addresses the power requirements of low-power wide-area ...

Implementing a light load efficiency improvement algorithm, the latest synchronous DC/DC buck converters from Diodes achieve an efficiency of 96% and deliver continuous load currents of 4 and 5A, ...

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 ...
