描述 Description
The NCP1030 and NCP1031 are a family of miniature high-voltage monolithic dc-dc converters with on-chip power switch and start-up circuits. The NCP103x family incorporates in a single IC all the active power, control logic and protection circuitry required to implement, with minimal external components, several switching regulator applications, such as a secondary side bias supply or a low power dc-dc converter.This controller family is ideally suited for 48 V telecom, 42 V automotive, 12 V input and Power Over Ethernet (PoE) applications. The NCP103x can be configured in any single-ended topology such as forward or flyback. The NCP1030 is targeted for applications requiring up to 3 W, and the NCP1031 is targeted for applications requiring up to 6 W.The internal error amplifier allows the NCP103x family to be easily configured for secondary or primary side regulation operation in isolated and non-isolated configurations. The fixed frequency oscillator is optimized for operation up to 1 MHz and is capable of external frequency synchronization, providing additional design flexibility. In addition, the NCP103x incorporates individual line undervoltage and overvoltage detectors, cycle by cycle current limit and thermal shutdown to protect the controller under fault conditions. The preset current limit thresholds eliminate the need for external sensing components.

简介
NCP1031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NCP1031DC-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。
