ACT88430 Advanced PMU for Microcontrollers and Solid State Drive Applications BENEFITS and FEATURES GENERAL DESCRIPTION Wide input voltage range The ACT88430 PMIC is an integrated ActivePMU power management unit. It is designed to power a wide Vin = 2.7V to 5.5V range of processors, including video processors, Complete integrated power solution FPGAs, peripherals, microcontrollers, and solid-state One 4A DC/DC Step-Down (Buck) Regulator drive applications. It is highly flexible and can be 2 reconfigured via I C for multiple applications without the Three 2.5A DC/DC Step-Down (Buck) Regulators need for PCB changes. The low external component count and high configurability significantly speeds time One 800mA LDO to market. Examples of configurable options include Two 200mA LDOs output voltage, startup time, slew rate, system level Space Savings sequencing, switching frequency, sleep modes, operat- ing modes etc. ACT88430 is programmed at the factory Fully integrated with default configuration. These settings can be High Fsw =2.25MHz or 1.125MHz 2 optimized for a specific design through the I C interface. Integrated sequencing The ACT88430 comes in several default configuration. Easy system level design Contact the factory for specific default configurations. Configurable sequencing The core of the device includes four DC/DC step down Seamless sequencing with external supplies converters using integrated power FETs, three Buck 1 Bypass Mode for 3.3V system level low-dropout regulators (LDOs), and an optional load switch. Each DC/DC regulator switches at 2.25MHz, compliance requiring only three small components for operation. Highly configurable The LDOs only require small ceramic capacitors. All are uP interface for status reporting and controllability 2 highly configurable via the I C interface. Programmable Reset and Power Good GPIOs The ACT88430 PMIC is available in a 5 x 5 mm 40 pin Flexible Sequencing Options QFN package or in a 4.17 x 3.17 mm 48-ball WLCSP 2 I C Interface 1MHz package. The ACT88430 can be optimized for many different pro- APPLICATIONS cessors including, but not limited to the following. The ACT88430 has CMI variations specifically designed to Computer Vision power the following.
