The ACT88321 PMIC is an integrated ActiveCiPSTM power management integrated circuit. It powers a wide range of processors, including solid-state drive controllers, video processors, FPGA’s, wearables, peripherals, and microcontrollers. The ACT88321 is optimized for SSD ,FPGA and LPDDR5 applications. 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 as low as 0.5V, startup time, slew rate, system level sequencing, switching frequency, sleep modes, operating modes etc. The core of the device includes three DC/DC step down converters using integrated power FETs, two low-dropout regulators (LDOs). Buck1 and LDO1 can be configured as a load switch. Buck 1 regulator switches at either 1.125MHz or 2.25MHz, Bucks 2/3 switch at 1.5MHz,2MHz,2.5MHz,3.3MHz , requiring only three small components for operation. The LDOs only require small ceramic capacitors. All are highly configurable via the I2C interface. Package compatible with PTH boards.

The Evaluation Tool Users Guide describes the characteristics and operation of the Qorvo ACT88327EVK1-101 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.
This EVK demonstrates the ACT88321VU101 ActivePMU power management IC.
The ACT88321 EVK1-101 Graphical User Interface (GUI) is packaged in a ZIP file that includes the software and all necessary drivers to communicate with the ACT88321EVK1 Evaluation Tool, as well as all descriptions how to use the tool.
