The ACT88320 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.
Advantages of our Modular Power PMU

The Evaluation Tool User Guide describes the characteristic and operation of the Active Semi ACT88320EVK1-101 evaluation kit (EVK).
It provides setup and operation instructions, schematic, layout, BOM, and test data.
To communicate with the EVK a USB Dongle and a Graphical User Interface (GUI) is provided. Download the GUI and all documentation and drivers here or in the Software TAB.
This EVK demonstrates the ACT88320QI101 ActivePMU power management IC.
The Graphical User Interface (GUI) is packaged in a ZIP file that includes the software and all necessary drivers to communicate with the ACT88320EVK1 Evaluation Tool, as well as all descriptions how to use the tool.
