Overview:
It is a step-down charging module. It supports the conversion of input voltage DC 6V-26V into DC 5.2V.Supports regulated output.
Specification:
Input voltage: DC6V-26V.
Output Voltage: DC5.2V (consider the charge line loss, the output is 5.2V, the load side is about 5V)
Output current: 3A (in the absence of heat sink device, the stable output current is 2A).
Operating temperature: -40 °C to 85 °C.
Quiescent current: 25uA.
Conversion efficiency: up to 98% (MAX)(I=7V,O=5V).
Switching frequency: 435KHz.
Display: with load LED indicator.
Input mode: IN+ input positive, IN- input negative.
Output port: USB (dual port).
Dimensions: 28 mm x 33 mm x 8 mm/1.1 x 1.3 x 0.31 inches.
Mounting pitch: 28.5 mm x 14 mm/1.12 x 0.55 inch (M2 screw holes).
Note:
The positive and negative poles cannot be reversed,and the input voltage cannot exceed 26V,otherwise the chip will be damaged.
Do not touch the sampling resistors and IC pins on the circuit board with your hands when powering on,otherwise it may cause sudden changes in the output voltage and damage the equipment.
The nominal 3A current will not burn the phone to burn the device. The actual charging current is determined by the phone or device. The charging current of most mobile phones is 0.8-1.5A.
Package contents:
3 x dual USB step down power supply modules.
