It is designed to power a wide range of processors, including video processors, FPGA’s, peripherals, microcontrollers, and solid-state drive 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, startup time, slew rate, system level sequencing, switching frequency, sleep modes, operat- ing modes etc. ACT88430 is programmed at the factory with default configuration. These settings can be optimized for a specific design through the I2C interface. The ACT88430 comes in several default configuration. Contact the factory for specific default configurations. The core of the device includes four DC/DC step down converters using integrated power FETs, three low-dropout regulators (LDOs), and an optional load switch. Each DC/DC regulator switches at 2.25MHz, requiring only three small components for operation. The LDOs only require small ceramic capacitors. All are highly configurable via the I2C interface. The ACT88430 PMIC is available in a 5 x 5 mm 40 pin QFN package or in a 4.17 x 3.17 mm 48-ball WLCSP package. The ACT88430 can be optimized for many different pro- cessors including, but not limited to the following. The ACT88430 has CMI variations specifically designed to power the following.
