The single-ended primary-inductor converter (SEPIC) is a well-known type of DC/DC converter that, in its standard form, can generate an output voltage greater than, less than, or equal to its input ...

Many times designers are given a set of non-isolated supply specifications where the output voltage falls between the minimum and maximum input voltage. They then have to decide between a flyback or ...

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 (Fig. 1). The SFB topology ...

The choice between a flyback or single-ended primary inductance converter (SEPIC) topology often ends with the designer choosing the most familiar one, but that’s not always the right option, say John ...

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 ...

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 ...

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 ...

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 ...

We have a love/hate relationship with LiIon batteries. They pack all this power in such a small and light package. But for running 3.3 V devices, they’re cumbersome. They need to be stepped down a ...
