NCP3012数据手册集成电路（IC）的PMIC-稳压器-DCDC开关式控制器规格书PDF

描述 Description

The NCP3012 is a PWM device designed to operate from a wide input range and is capable of producing an output voltage as low as 0.8V. The NCP3012 provides integrated gate drivers and an internally set 75kHz oscillator that has the capability to synchronous to an external frequency. The NCP3012 has an externally compensated transconductance error amplifier with an internally fixed soft start. The NCP3012 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 degrees out of phase clock signal to drive another NCP3012 (Master Mode). Protection features include lossless current limit and short circuit protection, output overvoltage and undervoltage protection, and input undervoltage lockout. The NCP3012 is available in a 14-pin TSSOP package.Ideal for noise sensitive applications which require minimal interference from the power supply.(Medical, Networking, etc.)

简介

NCP3012属于集成电路（IC）的PMIC-稳压器-DCDC开关式控制器。由制造生产的NCP3012DC-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。
