ACT8898 ® Product Brief, 29-Nov-10 Advanced PMU for Marvell Aspen FEATURES GENERAL DESCRIPTION • • • • • • • The ACT8898 is a complete, cost effective, highlyefficient ActivePMUTM power management solution, optimized for the unique power, voltagesequencing, and control requirements of the Marvell Aspen processor. Optimized for Marvell Aspen 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 1150mA of output current, while the third supports up to 1300mA. All four low-dropout linear regulators are highperformance, low-noise, regulators that supply up to 150mA, 150mA, 320mA, and 320mA, respectively. APPLICATIONS • • • • • Personal Navigation Devices Portable Media Players The ACT8898 is available in a compact, Pb-Free and RoHS-compliant TQFN55-32 package.
