4-Way Fast Charging Module USB Mobile Phone Charging Board

Overview & Features

. Soft start function. Conversion efficiency reaches 97%. 220Khz switching frequency. Built-in synchronous switch step-down converter chip. Output voltage range: 3V to 12V, automatically adjusted according to the fast charge protocol. Used in car chargers, fast charging adapters, smart power strips, solar chargers, etc. This module is a 4-way pressure drop fast charging module, please use 12V-30V DC power supply, and the positive and negative poles cannot be reversed. Input voltage range: 4.5V to 32V (the input voltage must be higher than the output voltage, because it is a voltage drop module). Multiple protections, high reliability, output over current, input over voltage, input under voltage, output short circuit protection, over temperature protection of the whole machine. The output has CV/CC characteristics (output current is less than the set value, output CV mode; output current is greater than the set value, output CC mode). PCB adopts FR-4 1.6mm thickness design, optimized layout and wiring, tight design, open window on the back for heat dissipation, low full load working temperature, standby current 0.013A, module has output voltage compensation function. Each of the four channels supports QC 3.0 fast charging protocol, and can support fast charging at the same time, and can output 5V/9V/12V (requires mobile phone protocol support) voltage, output current is adaptive, single channel power consumption 24W, 4 channels module Power consumption 96W..
