LTM4681集成電路（IC）的電源管理-專用規(guī)格書PDF中文資料

LTM4681屬于集成電路（IC）的電源管理-專用。由亞德諾半導(dǎo)體技術(shù)有限公司制造生產(chǎn)的LTM4681電源管理 - 專用專用型電源管理集成電路 (PMIC) 用于電源的控制或操作，適合特定或小范圍的目標(biāo)應(yīng)用，例如汽車氣囊管理、電容器組平衡、AC 公共電力監(jiān)控、存儲器總線端接、接地故障檢測、能量收集、小型引擎管理、處理器或芯片集專用電壓調(diào)節(jié)、負(fù)載突降保護、觸覺驅(qū)動器、熱電制冷器控制等。

DESCRIPTION

The LTM?4650-2 is a dual 25A or single 50A output stepdown

μModule? (micromodule) regulator with ±1.5

total DC output error. The package includes the switching

controller, power FETs, inductors, and all supporting components.

External compensation allows for fast transient

response to minimize output capacitance when powering

FPGAs, ASICs, and processors. AVP can further improve

transient response and reduce the output capacitance.

With synchronized multiphase parallel current sharing,

six LTM4650-2 devices can deliver up to 300A.

The LTM4650-2 is offered in a 16mm × 16mm ×

5.01mm BGA package with SnPb or RoHS-compliant

terminal finish.
