The Rockchip RK817-1 is a versatile power-management IC (PMIC) tailored for embedded systems utilizing Rockchip application processors. This highly integrated chip consolidates multiple essential functions into a single package, including multi-rail regulation (buck and LDO), a battery charger with power-path control, a fuel-gauge ADC subsystem, a real-time clock (RTC), and an integrated audio codec with headphone and Class-D speaker drive capabilities.
Designed for compact products like tablets, handhelds, and small SBCs, the RK817-1 simplifies power sequencing and reduces Bill of Materials (BOM) count and board area. It acts as the system's single point of truth for power state, enforcing programmable power-up and power-down sequences, providing always-on and switched rails, and monitoring battery and thermal conditions via an I2C interface.
The RK817-1 features four synchronous buck converter channels, operating at a 2 MHz switching frequency to allow for smaller inductors. It also includes multiple LDOs, one of which is a low-noise, high-PSRR type suitable for sensitive analog rails. The integrated switch-mode charger offers configurable CC/CV behavior and input limiting, enabling seamless operation from an adapter while charging the battery, with automatic fallback to battery power when needed. Dynamic voltage scaling is supported, allowing the operating system to adjust voltages based on SoC load.
