GENERAL DESCRIPTION

The 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 (2MHz), current-mode

PWM control architecture that requires a minimum

number of external components. Two DC/DCs are

capable of supplying up to 1100mA of output

current, while the third supports up to 1200mA. All

four low-dropout

linear

regulators

are

high-

performance, low-noise regulators that supply up to

320mA of output current.

The ACT8946A is available in a compact, Pb-Free

and RoHS-compliant TQFN55-40 package.
