SW3518S full protocol fast charging
Port A supports QC4+/QC4/QC3.0/QC2.0/AFC/FCP/SCP/VOOC/PE2.0/PE1.1/SFCP
A port can output 5V/5A
C port supports PPS/PD3.0/PD2.0
C port can output 20V5A (SW3518S) or 20V3A (SW3518)
Adding multiple 1206 chip capacitors can effectively filter out high frequency ripple
Fast charge indicator, power indicator
SOP-8 NMOS, AO4484 is used for testing, it can be replaced with MOS tube of similar specifications
Input 6-40V, recommended 25-36V, only voltage drop, the smaller the pressure difference, the smaller the heat
Electrolytic capacitors and 1206, 0805 capacitors need at least 25V withstand voltage, design and welding use 50V to provide redundancy
C6C7 in the schematic diagram are in different packages for easy purchase. C12C13 is the same, only need to weld 1
When soldering 3518S, pay attention to the grounding of the soldering iron tip, and use the air gun if possible, otherwise it is easy to encounter strange problems
