Dialog introduces the latest power converter series to further improve its smartphone fast charging solution

The DA9318 Power Converter IC Series offers 98% fast charging efficiency with minimal heat generation

Dialog Semiconductor, Inc. (Deutsche Stock Exchange: DLG), a highly integrated power management, AC/DC power conversion, charging and Bluetooth low-power technology provider, today announced the launch of its new line of power converter ICs, the DA9318, to complement its latest A family of highly efficient charging products released. The DA9318 significantly improves the fast charging efficiency and meets the increasingly high requirements for battery charging in the latest smartphones. Combined with Dialog's RapidChargeTM AC/DC power conversion chipset, the DA9318 converter complements Dialog's wall-to-battery charging solution and delivers breakthrough high-voltage direct charging efficiency.

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

This innovation is the industry's first and is ideally suited to address the design challenges of today's smart device battery capacity. At present, smartphone batteries are designed to provide longer battery life to support greater computing power, and their capacity is close to 4,000 mAh. Manufacturers are constantly looking for advanced charging solutions that provide high efficiency, safety and low heat. The DA9318 Series includes comprehensive security and protection features to ensure end-to-end system security from portable power adapters to smartphone batteries.

Udo Kratz, senior vice president and general manager of the mobile systems business unit at Dialog Semiconductor, said: "Dialog's leading technology in fast charging enables us to introduce the industry's first DA9318 rechargeable power converter family. This device and our iW656 USB-PD power supply Combining adapter interface ICs, Dialog now offers a complete wall-to-battery fast charging solution with breakthrough efficiency and significant cost savings. In addition, our efficiency improvements and over 18 integrated safety features also reduce heat generation and achieve even more Safe consumer applications."
