ACT8946A

Advanced PMIC for HiSilicon Processors

Qorvo's ACT8946A is a complete, cost effective, highly-efficient power management solution, optimized for the unique power, voltage-sequencing, and control requirements. It is ideal for a wide range of high performance portable handheld applications such as 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, POS terminals, medical devices and white goods. This device integrates the complete battery charging and management system with seven power supply channels.

This device features three step-down DC/DC converters and four low-noise, low-dropout linear regulators, along with a complete battery charging solution featuring the advanced ActivePath™ system-power selection function. 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 1100 mA of output current, while the third supports up to 1200 mA. All four low-dropout linear regulators are high-performance, low-noise regulators that supply up to 320 mA of output current.

ACT8946A is available in a compact, Pb-free and RoHS compliant TQFN55-40 package.
