NCP81119A規(guī)格書詳情

NCP81119A屬于集成電路(IC)的PMIC-穩(wěn)壓器-DCDC開關(guān)式控制器。由安森美半導(dǎo)體公司制造生產(chǎn)的NCP81119ADC-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。其他拓撲結(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。

The NCP81119 Multi?Phase buck solution is optimized for

Intel? VR12.5 compatible CPUs with user configurations of 4/3/2/1

phases. The controller combines true differential voltage sensing,

differential inductor DCR current sensing, input voltage

feed?forward, and adaptive voltage positioning to provide accurately

regulated power for both Desktop and Notebook applications. The

control system is based on Dual?Edge pulse?width modulation

(PWM) combined with DCR current sensing providing the fastest

initial response to dynamic load events at reduced system cost. It has

the capability to shed to single phase during light load operation and

can auto frequency scale in light load conditions while maintaining

excellent transient performance.

High performance operational error amplifiers are provided to

simplify compensation of the system. Patented Dynamic Reference

Injection further simplifies loop compensation by eliminating the need

to compromise between closed?loop transient response and Dynamic

VID performance. Patented Total Current Summing provides highly

accurate digital current monitoring.
