CS51031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

CS51031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CS51031DC-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 CS51031 is a switching controller for use in DC−DC converters. It can be used in the buck topology with a minimum number of external components. The CS51031 consists of a VCC monitor for controlling the state of the device, 1.0 A power driver for controlling the gate of a discrete P−Channel transistor, fixed frequency oscillator, short circuit protection timer, programmable Soft−Start, precision reference, fast output voltage monitoring comparator, and output stage driver logic with latch
