产品概述 返回TOPWr2嘉泰姆
CXTP65155是一款高性能的线性稳压器,能够做为DDR内存总线终端电源,和过去的开关解决方案比较,它显著的减少了器件数量,节省了板子的空间和系统成本。CXTP65155仅使用20μF or 30μF的输出电容就可以保持高速的瞬态响应。CXTP65155支持远程监测功能并满足所有DDR, DDR2, DDR3和低压的DDR3/DDR4 VTT总线终端电源的需求。CXTP65155具有过流和过温保护,另外,CXTP65155用漏极开路的PGOOD信号,监视输出的调整功能。当使能信号高有效时可以将VTT拉低,但是REFOUT还将保持有效,这是一种节能工作模式,在这种模式下,静态电流较低。CXTP65155有3mm x 3mm 的TDFN封装和SOP-8 (EP)封装。The CXTP65155 is a high performance linear regulator
designed to provide power for termination of a DDR
memory bus. It significantly reduces parts count,
board space and overall system cost over previous
switching solutions.
The CXTP65155 maintains a fast transient response
using only 20μF or 30μF output capacitance. The
CXTP65155 supports a remote sensing function and all
power requirements for DDR, DDR2, DDR3 and
Low Power DDR3/DDR4 VTT bus termination.
The CXTP65155provides current and thermal limits to
prevent damage to the linear regulator. Additionally,
The CXTP65155generates an open-drain PGOOD
signal to monitor the output regulation. An active
high enable pin EN can pull VTT low, but REFOUT
will remain active. A power savings advantage can be
obtained in this mode through lower quiescent
current.
The CXTP65155is available in the 3mm × 3mm
TDFN-10 and SOP-8 (EP) packages.
