ACT8897 ® Product Brief, 29-Nov-10 Advanced PMU for Samsung S5PC100, S5PC110 and S5PV210 Processors FEATURES GENERAL DESCRIPTION • Optimized for Samsung S5PC100, S5PC110 and The ACT8897 is a complete, cost effective, highlyefficient ActivePMUTM power management solution, optimized for the unique power, voltagesequencing, and control requirements of the Samsung S5PC100, S5PC110 and S5PV210 processors. S5PV210 Processors • • • • • • Three Step-Down DC/DC Converters Four Low-Dropout Linear Regulators I2CTM Serial Interface This device features three step-down DC/DC converters and four low-noise, low-dropout linear regulators. Advanced Enable/Disable Sequencing Controller Minimal External Components Tiny 5×5mm TQFN55-32 Package − 0.75mm Package Height − Pb-Free and RoHS Compliant 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 1100mA of output current, while the third supports up to 1200mA. All four low-dropout linear regulators are highperformance, low-noise, regulators that supply up to 150mA, 150mA, 250mA, and 250mA, respectively. APPLICATIONS • • • • • Personal Navigation Devices Portable Media Players Tablet Devices The ACT8897 is available in a compact, Pb-Free and RoHS-compliant TQFN55-32 package.
