Product Brief, 29-Nov-10
Advanced PMU for SiRF PrimaTM and Atlas IVTM FEATURES
Optimized for SiRF PrimaTM/Atlas IVTM Processors Three Step-Down DC/DC Converters Four Low-Dropout Linear
Regulators I2CTM Serial Interface Advanced Enable/Disable Sequencing Controller Minimal External Components Tiny 5×5mm TQFN55-32 Package − 0.75mm Package Height − Pb-Free and RoHS Compliant
GENERAL DESCRIPTION
The ACT8895 is a complete, cost effective, highlyefficient ActivePMUTM power management solution, optimized for the unique power, voltagesequencing, and control requirements of the SiRF PrimaTM and Atlas IVTM processors. 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 900mA of output current, while the third supports up to 700mA. All four lowdropout linear
regulators are high-performance, low-noise,
regulators that each supply up to 150mA. The ACT8895 is available in a compact, Pb-Free and RoHS-compliant TQFN55-32 package.
