In the face of severe environmental problems in the world and the gradual unification of charger standards by PD protocol, smart terminals led by Apple put forward the idea that all mobile terminals will no longer be sold with chargers. This has brought new opportunities and challenges to the existing charger market. According to the needs of the market, our company has launched a common silicon MOS and potassium nitride PD fast charging charger scheme. Our PD scheme has the advantages of high cost performance and good compatibility. Welcome to consult.
