NCV3011DTBR2G集成電路（IC）的PMIC-穩(wěn)壓器-DCDC開關(guān)式控制器規(guī)格書PDF中文資料

NCV3011DTBR2G屬于集成電路（IC）的PMIC-穩(wěn)壓器-DCDC開關(guān)式控制器。由安森美半導體公司制造生產(chǎn)的NCV3011DTBR2GDC-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 NCP3011 is a PWM device designed to operate from a wide

input range and is capable of producing an output voltage as low as

0.8 V. The NCP3011 provides integrated gate drivers and an internally

set 400 kHz oscillator. The NCP3011 has an externally compensated

transconductance error amplifier with an internally fixed soft?start.

The NCP3011 incorporates output voltage monitoring with a Power

Good pin to indicate that the system is in regulation. The dual function

SYNC pin synchronizes the device to a higher frequency (Slave

Mode) or outputs a 180° out?of?phase clock signal to drive another

NCP3011 (Master Mode). Protection features include lossless current

limit and short circuit protection, output overvoltage and undervoltage

protection, and input undervoltage lockout. The NCP3011 is available

in a 14?pin TSSOP package.
