LTC3882規(guī)格書詳情
LTC3882屬于集成電路(IC)的PMIC-穩(wěn)壓器-DCDC開關(guān)式控制器。由亞德諾半導(dǎo)體技術(shù)有限公司制造生產(chǎn)的LTC3882DC-DC 開關(guān)控制器PMIC(電源管理集成電路)DC 到 DC 開關(guān)式控制器是用于高效率電路的穩(wěn)壓 IC,其配置為生成高于(突升或步升)或低于(突降或步降)輸入電源的輸出電源電壓。其他拓?fù)浣Y(jié)構(gòu)可能包括:降壓-升壓、反激、正激、Cuk、SEPIC、全橋、半橋和推挽式。這些器件不同于需要最小電壓并“燒盡”多余電壓的線性穩(wěn)壓器。
DESCRIPTION
The LTC?3888/LTC3888-1/LTC3888-2 is a PMBus-compliant
dual loop DC/DC synchronous step-down switching regulator
controller with eight expandable phases supporting
a wide range of master/slave configurations. The controller
uses constant frequency current mode architecture to
provide excellent transient response and output regulation.
Each PWM master is capable of producing output voltages
from 0.3V to 3.45V with multiple phase configurations using
DrMOS devices that provide an output current monitor.
PMBus configuration and monitoring is supported by
LTpowerPlay? software. Programmable loop compensation
and built-in load step emulation facilitate setting bandwidth
based on input voltage and output load capacitance.
PMBus commands allow read back of input voltage, output
voltage and current, and operating status. Operating
parameters can be set via PMBus command or stored in
internal EEPROM for use at power up. Switching frequency,
phase configuration, output voltage (LTC3888/LTC3888-2),
output current limit (LTC3888-1) and device address can
also be set using external programming resistors.
