Advanced PMU for Samsung S3C6410
• Optimized for Samsung S3C6410 Processor
• Three Step-Down DC/DC Converters
• Four Low-Dropout Linear Regulators
• I2CTM Serial Interface
• Advanced Enable/Disable Sequencing Controller
• Minimal External Components
• Tiny 4x4mm TQFN44-32 Package
− 0.75mm Package Height − Pb-Free and RoHS Compliant

The ACT8896 is a complete, cost effective, highlyefficient ActivePMUTM power management solution, optimized for the unique power, voltagesequencing, 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 highefficiency, 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 lowdropout 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 TQFN44-32 package.
