Product Brief, 29-Nov-10 ACT8898 Advanced PMU for Marvell Aspen FEATURES • Optimized for Marvell Aspen Processors • Three Step-Down DC/DC Converters • Four Low-Dropout Linear Regulators • I2CTM Serial Interface • Advanced Enable/Disable Sequencing Controller • Minimal External Components • Tiny 5×5mm TQFN55-32 Package − 0.75mm Package Height − Pb-Free and RoHS Compliant APPLICATIONS • Personal Navigation Devices • Portable Media Players • Tablet Devices • Smart Phones • MIDs GENERAL DESCRIPTION The ACT8898 is a complete, cost effective, highly- efficient ActivePMU TM power management solution, optimized for the unique power, voltage- sequencing, and control requirements of the Marvell Aspen 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 1150mA of output current, while the third supports up to 1300mA. All four low-dropout linear regulators are high- performance, low-noise, regulators that supply up to 150mA, 150mA, 320mA, and 320mA, respectively. The ACT8898 is available in a compact, Pb-Free and RoHS-compliant TQFN55-32 package. TYPICAL APPLICATION DIAGRAM ® |
