Dialog Semiconductor launches new power converter series to further enhance its smartphone fast charging solutions

Dialog Semiconductor (Dialog: DLG), a supplier of highly integrated power management, AC/DC power conversion, charging and Bluetooth low energy technology, today announced the launch of the latest power converter IC series - DA9318, to complete its recently released high-efficiency charging product family. Let's learn about the relevant content with the power management editor.

Dialog Semiconductor launches new power converter series to further enhance its smartphone fast charging solutions

DA9318显著提高快速充电效率，可满足目前最新智能手机对电池充电越来越高的要求。结合Dialog的RapidCharge™ AC/DC电源转换芯片组，DA9318转换器完善了Dialog的墙到电池(wall-to-battery)充电解决方案，并提供突破性的高电压直接充电效率。

The key advantage of the DA9318 series is the conversion efficiency of up to 98%, which minimizes system power loss and heat generation, making compact consumer applications safer. Unlike the existing topology that uses low voltage and allows the charging current to pass directly through the cable, the design of the DA9318 series allows the use of standard 3A USB cables to achieve 6A charging current, which not only doubles the power but also significantly reduces the cost of fast charging applications by 35%. There are two products in this series: DA9318L provides a maximum charging current of 8A; DA9318M provides a maximum charging current of 10A. They support 35W and 44W charging power respectively.

This innovation is an industry first and is ideal for addressing the design challenges of increasing battery capacity in today’s smart devices. As smartphone batteries approach 4,000 mAh to provide longer battery life and support greater computing power, manufacturers are constantly looking for advanced charging solutions that provide high efficiency, safety, and low heat generation. The DA9318 series includes comprehensive safety and protection features to ensure end-to-end system safety from portable power adapters to smartphone batteries.

Dialog半导体公司高级副总裁兼移动系统业务部总经理Udo Kratz表示：“Dialog在快速充电领域的领先技术使我们能够推出业内首创的DA9318充电电源转换器系列。该器件与我们的iW656 USB-PD电源适配器接口IC相结合，Dialog现已提供具有突破性效率和显著节省成本的完整墙到电池快速充电解决方案。另外，我们的效率提升和超过18种集成的安全特性也使发热量下降，实现更安全的消费类应用。”
