Boost converter - Wikipedia

A boost converter (step-up converter) is a DC-to-DC power converter that steps up voltage (while stepping down current) from its input (supply) to its output (load). It is a class of switched-mode power supply (SMPS) containing at least two semiconductors (a diode and a transistor) and at least one energy storage element: a capacitor, inductor, or the two in combination.

Isolated DC/DC Converters | Mouser

Electronic systems often have several sub-circuits, each with its own voltage level requirement that may be higher or lower than the main power supply. Step-up (boost) converters raise a voltage to a higher level, while step-down (buck) converters lower it. Some DC/DC converter types can raise or lower voltage, such as "buck-boost" converters.

Single-ended primary-inductor converter - Wikipedia

The single-ended primary-inductor converter (SEPIC) is a type of DC/DC converter that allows the electrical potential at its output to be greater than, less than, or equal to that at its input.The output of the SEPIC is controlled by the duty cycle of the control transistor (S1).. A SEPIC is essentially a boost converter followed by an inverted buck-boost converter, therefore it is similar to ...
