18 Chipmakers Add AVS Protocol Support for iPhone 18 Pro — Fast-Charge Protocol IC Roundup for Adapter Designers
2026-09-14 · Compiled by Best IT Parts from public industry reporting
Apple has launched the iPhone 18 Pro and iPhone 18 Pro Max, and the wired fast-charge specification has shifted: Apple's own documentation requires a 60W-or-higher power adapter with Adjustable Voltage Supply (AVS) support plus a USB-C charging cable. AVS is now a must-have protocol capability for the next generation of USB-C chargers. Chongdiantou consolidated the published standalone fast-charge protocol ICs that already support AVS, listed by vendor, as a reference for charger development, solution design and component selection. The ACE 2026 Autumn Asia Charging Expo in Shenzhen will host a dedicated controller/IC zone covering USB PD protocol ICs, AC-DC and DC-DC power management, multi-port power sharing and power bank SoCs, with further AVS chips and reference designs expected to debut. For adapter makers and parts wholesalers, AVS silicon availability now determines which 65W-100W+ designs can ship for the iPhone 18 generation.
