Highly Flexible, Configurable, Advanced PMIC with Bypass Switch

    Key Features

    • 3 high efficiency buck converters
    • 2 LDOs
    • 4 configurable GPIOs
    • Integrated load bypass switches
    • I2C serial interface
    • Programmable power up & down
    • Minimal external components
    • Low standby power

    Qorvo's ACT88325 PMIC is an integrated ActivePMU™ power management unit. It is highly flexible and can be reconfigured via I2C for multiple applications without the need for PCB changes. The low external component count and high configurability significantly speeds time to market.

    Examples of configurable options include output voltage, startup time, slew rate, system level sequencing, switching frequency, sleep modes and operating modes. The core of the device includes 3 DC/DC step-down converters using integrated power FETs, and 2 low-dropout regulators (LDOs). Each regulator can be configured for a wide range of output voltages through the I2C interface.

    ACT88325 is programmed at the factory with a default configuration. The default settings can be optimized for a specific design through the I2C interface. Contact the factory for specific default configurations.

    The product includes features that allow flexibility for all system level configurations. The buck converter and LDO can be reconfigured as a bypass switch. It also contains a high power load switch controller. It's external power supply enable and power good interface allows seamless sequencing with external power supplies.

    ACT88325 is available in a 2.8 x 3.0 mm 36 ball WLCSP package with optimized pinout for easy PCB routing. The pinout allows PTH (Plated-Through Hole) under the package to enable optimize layout efficiency and reduce the required PCB layers for routing.
