A board-mount power supply is a type of power supply that is designed to be mounted directly onto a circuit board. This allows it to be integrated directly into a system, providing a convenient and compact way to supply power to the circuit. Board-mount power supplies are available in a range of different voltages and current ratings, and they can be used in a variety of applications. Some common types of board-mount power supplies include DC-DC converters, which convert a DC voltage to a different DC voltage, and AC-DC converters, which convert AC power from a wall outlet into DC power for use in electronic circuits. Board-mount power supplies are typically small and lightweight, making them ideal for use in portable devices and other applications where space is limited.
