Advanced PMIC for Atmel SAMA5Dx Series & SAM9 Series Processors ACT8945A
Qorvo's ACT8945A PMIC is a 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 automations, medical devices and white goods. This device features three step-down DC/DC converters and four low-noise, low-dropout (LDO) regulators, along with a complete battery charging solution featuring ActivePath™ system-power selection function. The three DC/DC converters utilize a high efficiency, fixed-frequency (2 MHz), current-mode PWM control architecture that reduces the number of external components. Two DC/DCs are capable of supplying up to 1100 mA of output current, while the third supports up to 1200 mA. All four LDO regulators are high performance, low-noise regulators capable of supplying up to 320 mA of output current.
