LM5141規(guī)格書詳情
LM5141屬于集成電路(IC)的PMIC-穩(wěn)壓器-DCDC開關(guān)式控制器。由德州儀器制造生產(chǎn)的LM5141DC-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。

3 Description
The LV5144 95-V, synchronous, buck controller
regulates from a high input voltage source or from an
input rail subject to high-voltage transients, minimizing
the need for external surge suppression components.
A high-side switch minimum on-time of 45 ns gives
large step-down ratios, enabling the direct step-down
conversion from a 48-V nominal input to low-voltage
rails for reduced system complexity and design
cost. The LV5144 continues to operate during input
voltage dips as low as 6 V, at nearly 100 duty
cycle if needed, making an excellent choice for highperformance
industrial controls, robotics, datacom,
and RF applications.
Forced-PWM (FPWM) operation eliminates switching
frequency variation to minimize EMI, while
user-selectable diode emulation lowers current
consumption at light-load conditions. The adjustable
switching frequency as high as 1 MHz can be
synchronized to an external clock source to eliminate
beat frequencies in noise-sensitive applications.
