一、About product

The 24V to 5.5V 5A Three USB ports step-down converter is an electronic device that converts a higher voltage (24V) to a lower voltage (5.5V) while maintaining a constant output current of up to 5 amps. This converter is designed with three USB ports, making it convenient for users to charge multiple devices at once.

The converter typically operates by adjusting the duty cycle of a switching transistor in order to regulate the output voltage. It may also include features such as over-voltage protection, over-current protection, and thermal protection to prevent damage to connected devices or the unit itself.

Overall, this type of converter is useful for a wide range of applications, including powering various electronics and charging mobile devices.
