Active-Semi ACT8894
The ACT8894 is a complete, cost effective, highlyefficient ActivePMUTM power management solution, optimized for the unique power, voltagesequencing, and control requirements of the Samsung S3C2416/S3C2450 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.FEATURES
● Optimized for Samsung S3C2416/S3C2450 ProcessorsGENERAL DESCRIPTION
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 150mA, 150mA, 250mA, and 250mA, respectively. The ACT8894 is available in a compact, Pb-Free and RoHS-compliant TQFN55-32 package.●
