The groundbreaking design of the DA9313 offers high peak efficiency and can power more than 50 W in less than 10 mm2 of board area, allowing developers to extend battery life and reduce charging time in direct charging and 2S lithium-ion (Li-ion) systems such as notebook PCs, DSLR cameras and portable Bluetooth speakers.
The power converter claims to be the first to achieve 98 percent efficiency and deliver 50-W enabling reduced system costs, PCB sizes and extended battery life in various applications of mobile devices. In comparison to traditional buck regulators, DA9313 enables greater than 20% efficiency improvement at light loads. The converter also enables a reduction in PCB size of more than 50 percent and reduces the system height to less than 1mm, which is mandated for the thinner next-gen mobile phones and Ultrabook’s coming to market. For systems that require up to 100 W of power, two DA9313 devices may also be put into an integrated master-slave configuration, providing designers with scalability for a wide range of system designs.
