The 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, operating modes etc. 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 ACT88326 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.

The ACT88326 PMIC is available in a 2.7 x 3 mm 36 pin WLCSP package.
