Advanced PMU for Samsung S3C6410
FEATURES
GENERAL DESCRIPTION
The ACT8936 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.
• Optimized for Samsung S3C6410 Processor
• Three Step-Down DC/DC Converters
• Four Low-Dropout Linear Regulators
• Integrated ActivePathTM Charger
• I2CTM Serial Interface
• Advanced Enable/Disable Sequencing Controller
• Minimal External Components
• Tiny 5×5mm TQFN55-40 Package
− 0.75mm Package Height
This device features three step-down DC/DC
converters and four low-noise, low-dropout linear
regulators, along with a complete battery charging
solution featuring the advanced ActivePathTM
system-power selection function.
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.
− Pb-Free and RoHS Compliant
APPLICATIONS
• Personal Navigation Devices
• Portable Media Players
• Tablet Devices
The ACT8936 is available in a compact, Pb-Free
and RoHS-compliant TQFN55-40 package.
• Smart Phones
• MIDs
