ACT88320 Advanced PMU with Inrush Control and Bypass Switch BENEFITS and FEATURES GENERAL DESCRIPTION The ACT88320 PMIC is an integrated ActivePMU Wide input voltage range power management unit. It is highly flexible and can be Vin = 2.7V to 5.5V 2 reconfigured via I C for multiple applications without the Blocking up to 20V need for PCB changes. The low external component Complete integrated power solution count and high configurability significantly speeds time One 4A DC/DC Step-Down with Bypass Mode to market. Examples of configurable options include Two 2.5A DC/DC Step-Down Regulators output voltage, startup time, system level sequencing, Two 200mA LDOs switching frequency, sleep modes, operating modes etc. High Power Load Switch Gate Driver with Slew The core of the device includes 3 DC/DC step down Rate Control converters using integrated power FETs, and 2 low-dropout regulators (LDOs). Each regulator can be Space Savings configured for a wide range of output voltages through Fully integrated 2 the I C interface. High Fsw = 2.25MHz or 1.125MHz ACT88320 is programmed at the factory with a default Integrated sequencing configuration. The default settings can be optimized for Easy system level design 2 a specific design through the I C interface. Contact the Configurable sequencing factory for specific default configurations. Seamless sequencing with external supplies The ACT88320 includes features that allow flexibility for Programmable Reset and Power Good GPIOs all system level configurations. The buck converter can Buck 1 Bypass Mode for 3.3V system level be reconfigured as a bypass switch. It also contains a compliance high power load switch controller. Its external power supply enable and power good interface allows Highly configurable seamless sequencing with external power supplies. uP interface for status reporting and controllability The ACT88320 PMIC is available in a 4 x 4 mm 32 pin Flexible Sequencing Options 2 QFN package.
