LTM4643电源-板安装的直流转换器规格书PDF中文资料

LTM4643属于电源-板安装的直流转换器。由亚德诺半导体技术有限公司制造生产的LTM4643直流转换器一种旨在将直流电压输入电平改变为一个或多个不同的直流电压输出电平的装置。

DESCRIPTION

The LTM®4710-1 is a quad DC/DC step-down μModule

(micromodule) regulator with 8A per output. The package

includes the switching controllers, the power MOSFETs,

inductors and all supported components. Operating over

an input voltage range of 2.5V to 5.5V. Channel 1’s output

voltage can be set by only one external resistor, where

the outputs for channel 2, channel 3, and channel 4 can

be set by two external resistors. All output voltages are

programmable up to 3.6V.

The LTM4710-1 employs Silent Switcher 2 architecture

with internal hot loop bypass capacitors to achieve both

low Electromagnetic Interference (EMI) and high efficiency.

The LTM4710-1 is packaged in a compact (6mm

× 12mm × 3.54mm) LGA with presolder package and is RoHS compliant.
