Advanced PMIC for Multi-Core Application Processors ACT8849
Qorvo's ACT8849 PMIC is a complete, cost effective, and highly-efficient ActivePMU™ power management solution optimized for the power, voltage sequencing and control requirements of the Samsung Exynos 4210 (S5PC210/S5PV310) and other application processors. The product 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 2.25 MHz, minimizing noise in sensitive applications and allowing the use of small external components. Dynamic Voltage Scaling (DVS) is supported either by dedicated control pins, or through the I2C interface to optimize the energy-per-task performance for the processor. This device also includes eight low-noise LDOs, one always-on LDO and an integrated backup battery charger to provide a complete power system for the processor. The power sequence and reset controller provides power-on reset, SW-initiated reset and power cycle reset for the processor. Multiple sleep modes with autonomous sleep and wake-up sequence control are supported. The thermal management and protection subsystem allows the host processor to manage the power dissipation of the PMU and the overall system dynamically. ACT8849 is available in a compact, Pb-free and RoHS compliant TQFN66-48 package.
