GENERAL DESCRIPTION

The ACT8897 is a complete, cost effective, highly-

efficient ActivePMUTM power management solution,

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 TQFN44-32 package.
