RK809-1

The RK809-1 is a Power Management IC (PMIC) developed by Rockchip, designed to efficiently manage power in embedded systems, particularly for Rockchip SoCs like the RK3588. It integrates multiple power rails, including DC-DC converters, LDOs (Low Dropout Regulators), and power sequencing, ensuring stable voltage supply to processors, memory, and peripherals.
Key features:
- Supports multi-phase power conversion for high efficiency.
- Offers programmable power sequencing for system stability.
- Includes over-voltage, under-voltage, and thermal protection.
- Optimized for low-power and high-performance applications, such as AIoT devices, tablets, and single-board computers.
The RK809-1 simplifies power design, reduces external components, and enhances reliability in Rockchip-based systems. For detailed specs, refer to Rockchip’s official datasheet.

The RK809-1 is a Power Management IC (PMIC) designed by Rockchip, commonly used in embedded systems.
- Pin Count: 42 pins (QFN package).
- Key Functions:
- Power Regulation: Multiple DC-DC buck converters (e.g., 3A/2A outputs) and LDOs for core, memory, and I/O voltages.
