Product Description
ACT8846QM490 Integrated Circuit Chip Advanced PMU For Multi-Core Application Processors
Product Description
ACT8846QM490 is a complete, cost-effective, and highly-efficient ActivePMU™ power management solution optimized for the power, voltage sequencing and control requirements of Rockchip RK31x8 application processor family.
ACT8846QM490 features four fixed-frequency, current-mode, synchronous PWM step-down converters that achieve peak efficiencies of up to 97%. These regulators operate with a fixed frequency of 2.25MHz, minimizing noise in sensitive applications and allowing the use of small external components. These buck regulators supply up to 2.8A of output current and can fully satisfy the power and control requirements of the multi-core application processor. Dynamic Voltage Scaling (DVS) is supported either by dedicated control pins, or through I2C interface to optimize the energy-per-task performance for the processor. This device also includes eight low-noise LDOs (up to 350mA per LDO), one always-on LDO and an integrated backup battery charger to provide a complete power system for the processor.
