GENERAL DESCRIPTION

The ACT8938 is a complete, cost effective, highly

efficient ActivePMU

TM power management solution,

optimized

for

the

unique

power,

voltage

sequencing, and control requirements of the Marvell

Aspen processor.

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

150mA, 150mA, 320mA and 320mA respectively.

The ACT8938 is available in a compact, Pb-Free

and RoHS-compliant TQFN55-40 package .
