ACT8865

Qorvo's ACT8865 PMIC is a complete, cost-effective, highly-efficient ActivePMU™ power management solution, optimized for the unique power, voltage-sequencing and control requirements of the Atmel SAMA5 and SAM9 based eMPU series processors. It is ideal for a wide range of high performance portable handheld applications such as smartwatches, wearables, POS terminals, tablet PCs, human-machine interfaces, control panels, smart grid infrastructures, network gateways, M2M systems, 2D barcode scanners, barcode printers, machine vision equipment, as well as home and commercial building automation, medical devices and white goods.

This device features three step-down DC/DC converters and four low-noise, low-dropout linear (LDO) regulators. The three DC/DC converters utilize a high-efficiency, fixed-frequency (2 MHz), current-mode PWM control architecture that requires a minimum number of external components. Two DC/DCs are capable of supplying up to 1150 mA of output current, while the third supports up to 1300 mA. All four LDO regulators are high-performance, low-noise, regulators that supply up to 320 mA.
