Product Brief, 05-Dec-12

ACT8892

Advanced Power Management Unit

FEATURES

− 0.75mm Package Height

− Pb-Free and RoHS Compliant

GENERAL DESCRIPTION

The ACT8892 is a complete, cost effective, highly-

efficient ActivePMU

that 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 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

320mA.

The ACT8892 is available in a compact, Pb-Free

and RoHS-compliant TQFN44-32 package.
