Power supplies in the board mount category are designed to be directly mounted onto a printed circuit board (PCB) and provide power to the components on the board. These power supplies typically have a compact design, low profile, and a high level of efficiency. They come in various form factors such as DC-DC converters, switching regulators, and linear regulators. The output voltage and current ratings vary depending on the specific application requirements. Board mount power supplies are commonly used in applications where space is limited, such as in portable electronics, IoT devices, and industrial control systems.
