ACT8870 Advanced PMU for Microcontrollers and Solid State Drive Applications BENEFITS and FEATURES GENERAL DESCRIPTION Wide input voltage range The ACT8870 PMIC is an integrated ActivePMU power management unit. It is designed to power a wide range Vin = 2.8V to 5.5V of processors, including Atmels SAMA5D2, FPGAs, Complete integrated power solution peripherals, microcontrollers, and solid-state drive One 4A DC/DC Step-Down (Buck) Regulator applications. It is highly flexible and can be reconfigured 2 via I C for multiple applications without the need for Three 2.5A DC/DC Step-Down (Buck) PCB changes. The low external component count and Regulators high configurability significantly speeds time to market. One 800mA LDO Examples of configurable options include output voltage, Two 200mA LDOs startup time, slew rate, system level sequencing, Space Savings switching frequency, sleep modes, operating modes etc. ACT8870 is programmed at the factory with default Fully integrated configuration. These settings can be optimized for a High Fsw =2.25MHz or 1.125MHz 2 specific design through the I C interface. The ACT8870 Integrated sequencing comes in several default configuration. Contact the Easy system level design 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 low-dropout regulators (LDOs), and an optional load Buck 1 Bypass Mode for 3.3V system level 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 2 uP interface for status reporting and highly configurable via the I C interface. controllability The ACT8870 PMIC is available in a 5 x 5 mm 40 pin Programmable Reset and Power Good GPIOs QFN package or a 3.2 x 4.2 mm 0.5mm 48 ball wafer Flexible Sequencing Options chip-scale package. 2 I C Interface 1MHz APPLICATIONS Microcontroller Applications Solid-State Drives FPGA Video Processor Data Sheet Rev. 7.0, Feb. 18, 2020 Subject to change without notice 1 of 49 www.qorvo.com ACT8870 Advanced PMU for Microcontrollers and Solid State Drive Applications TYPICAL APPLICATION DIAGRAM ACT8870 MCU BUCK1 (4.0A) BUCK2 (2.5A) BUCK3 (2.5A) DC/DC BUCK4 (2.5A) PG REGULATOR ENABLE LDO1 (800mA) LDO2 (200mA) LDO3 (200mA) SCL SDA nRESET IRQ Data Sheet Rev. 7.0, Feb. 18, 2020 Subject to change without notice 2 of 49 www.qorvo.com
