Rev 3, 28-June-17 ACT8892 Advanced Power Management Unit FEATURES Three Step-Down DC/DC Converters Four Low-Dropout Linear Regulators I2CTM Serial Interface Advanced Enable/Disable Sequencing Controller Minimal External Components Tiny 4×4mm TQFN44-32 Package 0.75mm Package Height Pb-Free and RoHS Compliant GENERAL DESCRIPTION The ACT8892 is a complete, cost effective, highly- efficient 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 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 320mA. The ACT8892 is available in a compact, Pb-Free and RoHS-compliant TQFN44-32 package.
