A7987TR規(guī)格書詳情
A7987TR屬于集成電路(IC)的PMIC-穩(wěn)壓器-DCDC開關(guān)式控制器。由意法半導(dǎo)體集團(tuán)制造生產(chǎn)的A7987TRDC-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。

描述 Description
The A7987 is a step-down monolithic switching regulator that can deliver up to 3 A
DC. The adjustable output voltage ranges from 0.8 V to VIN. The wide input voltage
range and the almost 100 duty cycle capability meet the fail-safe specifications for
automotive systems. The embedded switch-over feature on the VBIAS pin maximizes
efficiency at light load. The adjustable current limitation, designed to select the
inductor RMS current in accordance with the nominal output current, and the high
switching frequency capability make the size of the application compact. Pulse-bypulse
current sensing with digital frequency fold-back implements an effective
constant current protection over the different application conditions. The peak current
fold-back decreases the stress of the power components in heavy short-circuit
conditions. The PGOOD open collector output can also implement the output voltage
sequencing during the power-up phase. Multiple devices can be synchronized
sharing the SYNCH pin to prevent beating noise for low noise requirements such as
in infotainment applications.
