NCP81149MNTXG集成電路（IC）的特殊用途穩(wěn)壓器規(guī)格書PDF中文資料

NCP81149MNTXG屬于集成電路（IC）的特殊用途穩(wěn)壓器。由安森美半導(dǎo)體公司制造生產(chǎn)的NCP81149MNTXG特殊用途穩(wěn)壓器該系列產(chǎn)品用于電源控制、某種形式的轉(zhuǎn)換，適用于特定的復(fù)雜應(yīng)用。因此，各種產(chǎn)品特性集差異較大，包括空燃比傳感器接口、汽車交流發(fā)電機(jī)電壓調(diào)節(jié)、DDR 端接、液體透鏡控制、摩托車轉(zhuǎn)向信號控制、熱電 (peltier) 冷卻器控制、壓電觸覺控制、閥門控制、小型發(fā)動機(jī)管理等。

The NCP81149, a single?phase synchronous buck regulator,

integrates power MOSFETs to provide a high?efficiency and

compact?footprint power management solution for new generation

computing CPUs. The device is able to deliver up to 14 A TDC output

current on an adjustable output with SVID interface. Operating in high

switching frequency up to 1.2 MHz allows employing small size

inductors and capacitors while maintaining high efficiency due to

integrated solution with high performance power MOSFETs.

Current?mode RPM control with feedforward from both input power

supply and output voltage ensures stable operation over wide

operation condition. The NCP81149 is in a QFN48 6 x 6 mm package.
