Advanced PMU for Amlogic AML8726-M3 Processor

Amlogic AML8726-M3 processor. It is ideal for a wide

range of high performance portable handheld

applications such as tablet or pad devices. This device

FEATURES

• Three Step-Down DC/DC Converters

• Four Low-Dropout Linear Regulators

• Integrated ActivePath^TMCharger

• I²C^TMSerial Interface

• Advanced Enable/Disable Sequencing Controller

• Minimal External Components

• Tiny 5×5mm TQFN55-40 Package

− 0.75mm Package Height

− Pb-Free and RoHS Compliant

integrates the ActivePath^TMcomplete 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^TM

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 1150mA of output

current, while the third supports up to 1300mA. All

four low-dropout linear regulators are high-

performance, low-noise regulators that supply up to

80mA, 320mA, 320mA, 320mA, respectively.

GENERAL DESCRIPTION

The ACT8942 is a complete, cost effective, highly-

efficient ActivePMU^TMpower management solution,

optimized for the unique power, voltage-

sequencing, and control requirements of the

The ACT8942 is available in a compact, Pb-Free

and RoHS-compliant TQFN55-40 package.
