ACT88430 Register Definitions – CMI 101
The ACT88430 is an ActivePMU™ power management unit from Qorvo. It is designed to power a wide range of processors, FPGA’s, peripherals, and microcontrollers. The ACT88430 core includes four DC/DC step down converters using integrated power FETs and three LDOs. Each of these regulators can be configured for a wide range of output voltages through the I²C interface.
Today’s applications require more complexity in their startup and sequencing requirements. The ACT88430 I²C registers allow for customized configurations for these requirements. Although the ACT88430 is programmed at the factory with a default configuration, these settings can be changed through the I²C interface to provide customized configurations optimized for a specific processor and/or end application. IC configurability includes many options such as output voltage, startup sequencing, startup timing, slew rates, GPIO configuration, fault responses, and more. Qorvo identifies these configurations with a Code Matrix Index, CMI. An IC’s CMI is identified by the last three digits at the end of the orderable part number. Note that this application note is specific to the ACT88430’s CMI 101. Refer to the datasheet for the specific changes to other CMI version.
