USB Power Splitter Enhancement Module USB 5V and External 55x21 5V Power Supply MOS Circuit Power Enhancement Board

Features: When external 5V power supply is plug in, it automatically disconnects the 5V of the USB through a MOSFET, thereby enhancing the power supply and load-carrying capacity of the USB. When none external 5V power supply is plug in, the MOSFET is on, and the 5V output from the USB still occurs. At this time, it merely serves as a filter for the USB power supply. After being plugged into the power supply through the DC5V port, the USB port can drive a maximums load of 3A (the maximums current that the USB port can withstand is about 3A. USB is not suitable for larger currents, and the maximums current should not exceeds the current of the external power supply). The module is equipped with filter capacitors, thereby improving the power supply quality. It is equipped with automatic switching circuit, ensuring that USB5V and external 5V do not conflict.
