QFN-68-EP(7x7) Power Management - Specialized RoHS
The RK809-5 is a highly integrated Power Management Integrated Circuit (PMIC) from Rockchip designed for multi-core processor systems and embedded applications. It provides a complete power management solution by integrating multiple high-efficiency DC-DC buck converters, LDO regulators, power sequencing logic, battery fuel gauging, RTC functionality, and audio codec capabilities into a single device. The RK809-5 is commonly used alongside Rockchip SoCs in single-board computers, tablets, AIoT devices, and industrial embedded systems.
