Planar Transformer Meets Co-Packaged GaN: 65W AC Brick Power Supply Debuts
2026-08-20 · Compiled by Best IT Parts from public industry reporting
Chinese semiconductor suppliers are pushing the integration envelope in compact AC power supplies. Xinxian Semiconductor has developed a 65W AC brick power supply combining its own planar transformer with the INJOINIC IP2075_38D co-packaged GaN power chip. The planar transformer shrinks the magnetic component while improving efficiency and thermal performance, while the integrated GaN power stage cuts component count and design complexity versus discrete solutions. The article details the platform architecture and how the pairing enables a compact, high-efficiency 65W AC-DC brick suited to adapters and embedded power applications. For power adapter OEMs, component distributors, and B2B buyers tracking next-generation AC-DC platforms, it highlights a promising direction in planar magnetics and GaN integration for cost-effective, space-constrained designs.
