ACT8862

Advanced PMU for Amlogic AML8726-M3

FEATURES

− 0.75mm Package Height

− Pb-Free and RoHS Compliant

GENERAL DESCRIPTION

The ACT8862 is a complete, cost effective, highly-

efficient ActivePMU

optimized

for

the

unique

power,

voltage-

sequencing, and control requirements of the Amlogic

AML8726-M3 processor.

This device features three step-down DC/DC

converters and four low-noise, low-dropout linear

regulators.

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 and 320mA, respectively.

The ACT8862 is available in a compact, Pb-Free

and RoHS-compliant TQFN44-32 package.
