GENERAL DESCRIPTION

The ACT8942 is a complete, cost effective, highly-

efficient ActivePMU

TM power management solution,

optimized

for

the

unique

power,

voltage-

sequencing,

and

control

requirements

of

the

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

integrates the ActivePath

TM 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

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.

The ACT8942 is available in a compact, Pb-Free

and RoHS-compliant TQFN55-40 package.
