Southchip's POWERQUARK® series chips are applied in UGREEN's 65W GaN fast-charging adapter
Recently, UGREEN's 65W GaN fast-charging adapter powered by Southchip's POWERQUARK® series chips was released. This USB-C GaN charging adapter supports a wide voltage range of 100V-240V, has a compact size that fits in the palm of your hand, and weighs only 108g. The lightweight and small form factor, combined with its powerful performance, vividly demonstrate the high integration and high efficiency features of the POWERQUARK® series chips.
The current pain points of charging adapters mainly include: slow charging speed, which fails to meet users' needs for fast charging; poor portability, as multiple adapters are required for different devices; and insufficient compatibility, due to the lack of universal fast-charging protocols across different brands.
The Southchip POWERQUARK series is the first domestic isolated flyback fully integrated solution, integrating five independent functions—primary-side controller, GaN power switch, high-speed isolated digital communication module, synchronous rectification controller, and protocol—into a single chip.
As a high-performance fast-charging solution, POWERQUARK integrates the functions previously achievable only with five separate chips into a single chip, thanks to its ultra-high integration. This helps charger developers more aggressively reduce the product size. Meanwhile, POWERQUARK's soft-switching technology and active synchronous rectification can effectively reduce system EMI and enhance system reliability, helping engineers shorten the development cycle and improve development efficiency. POWERQUARK is a fast-charging partner you can trust.
