NCP1579中文资料同步降压控制器，低电压数据手册ONSEMI规格书

描述 Description

The NCP1579 is a low cost PWM controllers designed to operate from a 5V or 12V supply. These devices are capable of producing an output voltage as low as 0.8V.These 8 pin devices provide an optimal level of integration to reduce size and cost of the power supply.The NCP1579 provides a 1A gate driver design and an internally set 275kHz oscillator.Other efficiency enhancing features of the gate driver include adaptive non overlap circuitry.The NCP1579 also incorporates an externally compensated error amplifier and a capacitor programmable soft start function.Protection features include programmable short circuit protection and under voltage lockout.

简介

NCP1579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NCP1579DC-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。
