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 TQFN55-32 package.
