Regulators and Power Supplies

Subcategories

Buck-boost and SEPIC converters work with input voltages that are higher than, equal to, or lower than the regulated output voltage, making them especially well-suited for battery-powered applications in which the battery voltage begins above the desired output voltage and drops below the target as the battery discharges.

Boost converters generate a regulated output voltage that is higher than the input voltage.

Switching buck converters reduce an input voltage to a lower, regulated voltage much more efficiently than linear regulators.

The Hydra is a triple-output power converter from CH Robotics designed to make it easier to get the power you need for your next project. With its palm-sized aluminum case, the Hydra provides all the flexibility of a bench-top supply and only uses a fraction of the desk space. Each of the three outputs can supply about 12 W maximum at voltages ranging from 2.5 V to 14 V, and they can be controlled from a computer via USB or a microcontroller via serial.
