ACT8892 Product Brief, 05-Dec-12 Advanced Power Management Unit FEATURES GENERAL DESCRIPTION • • • • • • The ACT8892 is a complete, cost effective, highlyefficient ActivePMUTM power management solution that is ideal for a wide range of high performance portable handheld applications such as tablet or pad devices. Three Step-Down DC/DC Converters Four Low-Dropout Linear Regulators I2CTM Serial Interface Advanced Enable/Disable Sequencing Controller This device features three step-down DC/DC converters and four low-noise, low-dropout linear regulators. Minimal External Components Tiny 4×4mm TQFN44-32 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 320mA. The ACT8892 is available in a compact, Pb-Free and RoHS-compliant TQFN44-32 package.
