NCP1587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 NCP1587 and NCP1587A are 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 NCP1587 and NCP1587A provide a 1A gate driver design and an internally set 275kHz (NCP1587) and 200kHz (NCP1587A) oscillator.Other efficiency enhancing features of the gate driver include adaptive non overlap circuitry.The NCP1587 and NCP1587A also incorporate 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

NCP1587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NCP1587DC-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。
