ACT8937数据手册Qorvo中文资料规格书

描述 Description

The ACT8937 is a complete, cost effective, highlyefficient ActivePMUTM power management solution,optimized for the unique power, voltagesequencing,and control requirements of the Samsung S5PC100, S5PC110 and S5PV210 processors.\r
\r
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.\r
\r
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 1100mA of output current, while the third supports up to 1200mA. All four low-dropout linear regulators are highperformance, low-noise regulators that supply up to 150mA, 150mA, 250mA, and 250mA, respectively.\r
\r
The ACT8937 is available in a compact, Pb-Free and RoHS-compliant TQFN55-40 package.
