Which topology do you chose when your specification calls for a non-isolated power supply and the output voltage falls between the minimum and maximum input voltage? Is the tried-and-true flyback used ...

The LT8711 [1] is a DC/DC controller that supports synchronous buck, boost, SEPIC and ZETA topologies, or nonsynchronous buck-boost topologies. Analog Devices offers numerous synchronous buck and ...

Two critical issues, efficiency and transient response, continue to tag-team the power-electronics arena. CUI takes them on with its patented SEPIC-fed buck (SFB) converter. Two critical issues, ...

Zeta, or ‘inverse sepic’, is another one of those dc-dc converters, like Cuk and Sepic, that have a capacitor in series with the power path. Both zeta and Sepic have the same transfer function: ...

These are partly line-bound at the input side and output side of the voltage converter, but partially these are also radiated. Those interferences are mainly caused by the rapid switching edges. They ...

SEPIC (Single Ended Primary Inductance Converter) topology is a good choice for automotive power systems that require an output voltage between the low and high values of the input voltage. SEPIC ...

There are multiple solutions in which line current is sinusoidal. In addition, in the recent years, a great number of circuits have been proposed with non-sinusoidal line current. In this paper, a ...

Linear Technology has brought out the LT8494, a current mode, fixed frequency SEPIC/boost DC-DC converter with an internal 2A, 70V switch. Quiescent current of only 7µA makes the device suitable for ...

Linear Technology Corporation announces the LT8330, a current mode, 2MHz step-up DC/DC converter with an internal 1A, 60V switch. It operates from an input voltage range of 3V to 40V, making it ...

Power factor correction (PFC) converters are critical components in modern power electronics, designed to improve the efficiency and quality of power distribution by minimising harmonic distortion in ...
