MCP1631集成电路（IC）的稳压器-DC-DC开关稳压器规格书PDF中文资料

MCP1631属于集成电路（IC）的稳压器-DC-DC开关稳压器。由微芯科技股份有限公司制造生产的MCP1631稳压器 - DC-DC 开关稳压器DC-DC 开关稳压器 PMIC（电源管理集成电路）产品族中的产品是元器件级设备，用于需要稳定 DC 输入电压和/或将其转换为不同幅度的输出电压的应用。这些器件与称为“控制器”PMIC 的类似产品的区别在于集成了主开关元件，设备提供的电力会通过该元件。

General Description

The MCP1631/MCP1631V is a high-speed analog pulse width modulator (PWM) used to develop intelligent power systems. When combined with a microcontroller, the MCP1631/MCP1631V will control the power system duty cycle providing output voltage or current regulation. The microcontroller can be used to adjust output voltage or current, switching frequency and maximum duty cycle while providing additional features making the power system more intelligent, robust and adaptable.
