Key Features

  • 3 step-down DC/DC converters
  • 4 low dropout linear regulators
  • Integrated ActivePath™ charger
  • I2C™ serial interface
  • Advanced enable/disable sequencing
  • Minimal external components
  • Pb-Free and RoHS compliant

Qorvo's ACT8931A PMIC is a complete, cost effective, highly efficient ActivePMU™ power management solution, optimized for the unique power, voltage sequencing, and control requirements of the Rockchip RK2928/RK2926 processors.

The product features three step-down DC/DC converters and four low-noise, low-dropout linear regulators, along with a complete battery charging solution featuring the advanced ActivePath™ system-power selection function. The three DC/DC converters utilize a high efficiency, fixed-frequency (2 MHz), current-mode PWM control architecture that requires a minimum number of external components. Two DC/DCs are capable of supplying up to 1100 mA of output current, while the third supports up to 1200 mA. All four low-dropout linear regulators are high performance, low-noise regulators that supply up to 320 mA of output current.

ACT8931A is available in a compact, Pb-free and RoHS compliant TQFN55-40 package.
