The synchronous architecture of Magnachip’s boost converter achieves both high efficiency and low quiescent current. By using low-resistance high-side and low-side synchronous switches, the boost ...

However, this method will not work for boost topologies because the total current into the converter is greater ... In these figures, the lower waveforms (showing voltages on J5) reflect the ...

A negative-output voltage converter, however, can provide an alternative that you should not overlook. Figure 1 shows the schematic of an inverting buck-boost circuit driving three LEDs in a ...

keeping the boost converter switched off. In this state, the output voltage is equal to the input voltage. A current sense resistor is then installed in the output path. When a load is connected ...

A power-factor corrector accomplishes this by precisely controlling its input current to match the waveform of the input voltage. Boost converters can be driven in discontinuous conduction mode ...

Linear Tech has brought out a synchronous current mode monolithic buck-boost converter that delivers up to 5A of continuous output current in buck mode from a wide variety of input sources, including ...

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 ...

This is the third time that Cheng’s team has published their work in ISSCC, entitled "A 98.6%-Peak-Efficiency 1.47A/mm 2 Current-Density Buck-Boost Converter with Always Reduced Conduction Loss".
