ACT8933 Advanced PMU for CoreLogic LUCY • Optimized for CoreLogic LUCY Processors • Three Step-Down DC/DC Converters • Four Low-Dropout Linear Regulators • Integrated ActivePathTM Charger • I2CTM Serial Interface • Advanced Enable/Disable Sequencing Controller • Minimal External Components • Tiny 5x5mm TQFN55-40 Package − 0.75mm Package Height − Pb-Free and RoHS Compliant The ACT8933 is a complete, cost effective, highlyefficient ActivePMUTM power management solution, optimized for the unique power, voltagesequencing, and control requirements of the CoreLogic LUCY processors. This device features three step-down DC/DC converters and four low-noise, low-dropout linear regulators, along with a complete battery charging solution featuring the advanced ActivePathTM system-power selection function. 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 900mA of output current, while the third supports up to 700mA. All four lowdropout linear regulators are high-performance, low-noise regulators that supply up to 250mA each. The ACT8933 is available in a compact, Pb-Free and RoHS-compliant TQFN55-40 package.
