RK808-D

The RK808-D is a Power Management IC (PMIC) designed by Rockchip, primarily for use with their processors. Key features include:
- Multi-Output Power Rails: Supports multiple voltage outputs (e.g., DCDC, LDOs) for CPUs, GPUs, memory, and peripherals.
- High Efficiency DCDC Converters: Typically 4-5 buck converters (e.g., 1.0V, 1.8V, 3.3V) with >90% efficiency.
- Low-Dropout Regulators (LDOs): Multiple LDOs for stable low-noise power (e.g., 1.2V, 3.3V).
- Dynamic Voltage Scaling (DVS): Adjusts CPU/GPU voltage for power optimization.
- I²C/SPI Interface: Programmable control for voltage and power sequencing.
- Power Sequencing: Ensures proper startup/shutdown of system components.
- Protections: Over-current, over-voltage, under-voltage, and thermal shutdown.
- Low Power Modes: Supports sleep/standby for energy efficiency.
Commonly paired with Rockchip SoCs (e.g., RK3399, RK3566), it’s used in tablets, AIO PCs, and embedded systems. Compact packaging (e.g., QFN-68) suits space-constrained designs.

The RK808-D is a Power Management IC (PMIC) with 68 pins in a QFN package. Key functions include:
