USB Output Power Supply DC-DC Module Step-down Board Charging Board Step-Down Buck Step-down Module

Label:Yes Weight: 3g. Packing List:1Pc USB Step-down Charging Module The input voltage: 4.5V-28V; Conersion efficiency: 96%; Product model: LM2596 DC-DC Buck module; Size: 44mm*21mm*14mm; Switching frequency: 1.5MHz; Working temperature: -45~+85; The output voltage: 0.8V-20V; The output current: 3A(MAX); Input voltage range: DC 3V to 40V (input voltage must be more than 1.5V above the output voltage is high. Can not boost). Input + --- IN +. Enter negative --- IN-. Output Voltage Range: Output + --- OUT. Output negative --- OUT. 1.5 to 35V DC voltage is continuously adjustable, the maximum output current of 3A. Product Description: Advantages: All use of imported SMD aluminum electrolytic capacitors, high-power high-Q inductors. Additionally, each a plate have been strictly technical tests, all testing has been completed using a separate anti-static protection bags package. Specially designed two screw holes. Four input and output pads are provided with a pin fixing hole spacing 100mil are integer multiples, convenient volume applications in the product; Note: working long hours is recommended for use in less than 2.5A of current, and coupled with the heat sink (10W output above); Since the step-down module, in order to ensure stable output, keep a minimum 1.5V differential. Voltage Regulator: Access to power (3-40V), adjust the blue potentiometer knob (clockwise rotation generally boost, buck counterclockwise rotation) and with a multimeter to monitor the output voltage reaches the required voltage. Wiring: 1. welding, welded directly to the power line input (output) port; 2. solder pins, or pins can be inserted through the lead insertion use in tunnel plate; soldered directly to the PCB after another or add pin
