CS5155GDR16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CS5155GDR16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)動機管理等。

The CS5155 is a 5?bit synchronous dual N?Channel buck controller. It is designed to provide unprecedented transient response for today’s demanding high?density, high?speed logic. The regulator operates using a proprietary control method, which allows a 100 ns response time to load transients. The CS5155 is designed to operate over a 4.25?14 V range (VCC) using 12 V to power the IC and 5.0 V as the main supply for conversion.

The CS5155 is specifically designed to power Pentium? II processors and other high performance core logic. It includes the following features: on board, 5?bit DAC, short circuit protection, 1.0 output tolerance, VCC monitor, and programmable Soft Start capability. The CS5155 is backwards compatible with the 4?bit CS5150, allowing the mother board designer the capability of using either the CS5150 or the CS5155 with no change in layout. The CS5155 is available in 16 pin surface mount and DIP packages.
