基于ACT8937设计的高效7路DC电源技术_技术

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.

The ACT8937 is available in a compact, Pb-Free and RoHS-compliant TQFN55-40 package.

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 supply up to 150mA, 150mA, 250mA, and 250mA, respectively.
