MCP1630T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

MCP1630T属于集成电路（IC）的PMIC-稳压器-DCDC开关式控制器。由美国微芯科技公司制造生产的MCP1630TDC-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。

描述 Description

The MCP1630/V is a high-speed Pulse Width Modulator (PWM) used to develop intelligent power systems. When used with a microcontroller unit (MCU), the MCP1630/V will control the power system duty cycle to provide output voltage or current regulation. The MCU can be used to adjust output voltage or current, switching frequency, maximum duty cycle and other features that make the power system more intelligent.
