SW3518S full protocol fast charging power module 100W

Overview

The module can be directly plugged into the DC5.5x2.1 connector. It can charge all kinds of mobile phones, has high power and a relatively comprehensive agreement.
The maximum theoretical input voltage is 40V. I use a 24V150W switching power supply and it is fully loaded with 100W.

A dual-port charging solution that supports PD's multiple fast charging protocols.

SW3518S is a highly integrated multi-fast charging protocol dual-port charging chip that supports fast charging output from any A+C port and supports independent current limiting for dual ports. It integrates a 5A high-efficiency synchronous buck converter, supports multiple fast charging protocols such as PPS/PD/QC/AFC/FCP/SCP/PE/SFCP/VOOC, CC/CV mode, and dual-port management logic.
