FEATURES - - - - - - Three Step-Down DC/DC Converters Four Low-Dropout Linear Regulators I2CTM Serial Interface Advanced Enable/Disable Sequencing Controller Minimal External ponents Tiny 5×5mm TQFN55-32 Package - 0.75mm Package Height - Pb-Free and Ro HS pliant GENERAL DESCRIPTION The ACT8890 is a plete, cost effective, highlyefficient Active PMUTM power management solution, for portable handheld equipment such as Smartphones, Mobile Internet Devices (MID), e Books 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 ponents. Two DC/DCs are capable of supplying up to 1150m A of output current, while the third supports up to 1300m A. All four low-dropout linear regulators are highperformance, low-noise, regulators that supply up to 320m A each. The ACT8890 is available in a...
