ACT8890 Advanced PMU for Portable Handheld Equipment • 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 ACT8890 is a complete, cost effective, highlyefficient ActivePMUTM power management solution, for portable handheld equipment such as Smartphones, Mobile Internet Devices MID , eBooks and etc. 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 each. The ACT8890 is available in a compact, Pb-Free and RoHS-compliant TQFN44-32 package.
