GENERAL DESCRIPTION

The ACT8896 is a complete, cost effective, highly-

efficient ActivePMUTM power management solution,

optimized for the unique power, voltage-

sequencing, and control requirements of the

Samsung S3C6410 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 900mA of output current,

while the third supports up to 700mA. All four low-

dropout linear regulators are high-performance,

low-noise, regulators that supply up to 150mA,

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

The ACT8896 is available in a compact, Pb-Free

and RoHS-compliant TQFN55-32 package.
