NCV3020B集成电路（IC）的PMIC-稳压器-DCDC开关式控制器规格书PDF中文资料

NCV3020B属于集成电路（IC）的PMIC-稳压器-DCDC开关式控制器。由安森美半导体公司制造生产的NCV3020BDC-DC 开关控制器PMIC（电源管理集成电路）DC 到 DC 开关式控制器是用于高效率电路的稳压 IC，其配置为生成高于（突升或步升）或低于（突降或步降）输入电源的输出电源电压。其他拓扑结构可能包括：降压-升压、反激、正激、Cuk、SEPIC、全桥、半桥和推挽式。这些器件不同于需要最小电压并“烧尽”多余电压的线性稳压器。

The NCP3020 is a PWM device designed to operate from a wide

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

0.6 V. The NCP3020 provides integrated gate drivers and an internally

set 300 kHz (NCP3020A) or 600 kHz (NCP3020B) oscillator. The

NCP3020 also has an externally compensated transconductance error

amplifier with an internally fixed soft−start. Protection features

include lossless current limit and short circuit protection, output

overvoltage protection, output undervoltage protection, and input

undervoltage lockout. The NCP3020 is currently available in a SOIC−8 package.
