USB Power Boost Module Enhance Supply and Load Capacity Built-in Automatic Switching MOS Circuit

USB Power Boost Module Enhance Supply and Load Capacity Built-in Automatic Switching MOS Circuit Description

After the power supply is plugged in through DC5V port, the USB port can drive the maximum 3A load (the maximum withstand current of USB port is about 3A, so it is not suitable to use USB for larger current, and the maximum current does not exceed the current of external power supply). The module is equipped with high-quality filter capacitor, thus improving the quality of power supply. Built-in automatic switching MOS circuit, USB5V and external 5V not . USB power supply enhancement module, 5V external power supply. DC 5.5x2.1mm power supply interface and USB3.0 interface. Product features: Automatically switch the 5V power supply of USB and the external DC5V power supply. When the external 5V power supply is plugged in, the 5V of USB is automatically disconnected through MOS tube, which enhances the power supply and loading capacity of USB. When the external 5V power supply is not plugged in, the MOS tube is turned on, and the 5V of USB is still output, which only plays the role of filtering the USB power supply.
