| Advanced Power Management Unit • Three Step-Down DC/DC Converters • Four Low-Dropout Linear Regulators • I2CTM Serial Interface • Advanced Enable/Disable Sequencing Controller • Minimal External Components • Tiny 4x4mm TQFN44-32 Package 0.75mm Package Height Pb-Free and RoHS Compliant 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. This device features three step-down DC/DC converters and four low-noise, low-dropout linear regulators. 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.
