GENERAL DESCRIPTION

The ACT8896 is a complete, cost effective, highly-efficient ActivePMU TM 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.
