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… ...

Some buck converters will use two FETs. Some will reduce switching frequency based on load. Then there are boost topologies for going from a lower voltage to a higher one and even boost-buck when ...

Buck-boost converter topologies fit into a wide range of applications. Whether you are charging a battery from a battery, powering a string of LEDs, or running a handheld device from a single cell, ...

Due to the increased dropout voltage of the buck converter and the lower plateau voltage of the Lithium-ion battery, there was effectively no difference in battery life between the two converters at ...

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 can achieve efficiencies of 95% or higher, far surpassing linear regulators, which typically fall in the 40% range. The basic buck converter (Fig. 1a) ...

DALLAS, Sept. 30, 2019 /PRNewswire/ -- Texas Instruments (TI) (Nasdaq: TXN) today introduced a family of four high-efficiency, low-quiescent-current (I Q) buck-boost converters that feature tiny ...

ST has brought out a 1A buck converter for low-voltage loads in smart meters, home appliances and industrial converters The’ DCP3601 miniature monolithic buck converter is claimed to have over 90% ...

Check out a new feature newly loaded online at ElectronicsWeekly.com – Buck-boost converters change with the times. As serial-fabric technologies become the limiting factor to system performance, he ...
