MCP16323集成电路（IC）的稳压器-DC-DC开关稳压器规格书PDF中文资料

MCP16323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MCP16323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。

Description

The MCP16323 is a highly integrated, high-efficiency, fixed frequency, synchronous step-down DC-DC converter in a 16-pin QFN package that operates from input voltages up to 18V. Integrated features include a high-side and low-side N-Channel switch, fixed frequency Peak Current Mode Control, internal compensation, peak current limit, VOUT overvoltage protection and overtemperature protection. Minimal external components are necessary to develop a complete synchronous step-down DC-DC converter power supply.
