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. Key Features Five high-efficiency synchronous buck converters with fast transient response. Nine low-dropout (LDO) voltage regulators for powering sensitive analog and digital circuits. Integrated battery fuel gauge for battery capacity monitoring. Configurable power-up and power-down sequencing (OTP programmable). Dynamic Voltage Scaling (DVS/DVFS) support via I²C interface. Integrated Real-Time Clock (RTC) with 32.768 kHz crystal oscillator support. Two integrated load switches for peripheral power control. Over-current, over-voltage, and thermal protection features. Built-in audio CODEC with headphone driver and Class-D amplifier support. Designed to minimize external component count and simplify power system design. QFN-68-EP (7 mm × 7 mm) package. #RK8095 #RK809 #Rockchip #PMIC #PowerManagementIC #BatteryManagement #AudioCodec #RTC #DVFS #EmbeddedSystems #SingleBoardComputer #IoT #IndustrialElectronics #PowerSupplyDesign #ElectronicsEngineering
