FEATURES

S5PV210 Processors

− 0.75mm Package Height

− Pb-Free and RoHS Compliant

APPLICATIONS

GENERAL DESCRIPTION

The ACT8897 is a complete, cost effective, highly-

efficient ActivePMU

optimized

for

the

unique

power,

voltage-

sequencing,

and

control

requirements

of

the

Samsung

S5PC100,

S5PC110

and

S5PV210

processors.

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 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

150mA, 150mA, 250mA, and 250mA, respectively.

The ACT8897 is available in a compact, Pb-Free

and RoHS-compliant TQFN55-32 package.
