    Qorvo's ACT88326 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.

    ACT88326 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 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.

    ACT88326 is available in a 2.8 x 3 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.
