MCP16312中文资料30V/1A PWM Synchronous Buck Regulator数据手册Microchip规格书

描述 Description

The MCP16311 is a compact, high-efficiency, fixed frequency PWM/PFM, synchronous step-down DC-DC converter in a 8-pin MSOP, or 2 x 3 TDFN package that operates from input voltage sources up to 30V.  Integrated features include a high-side and a low-side switch, fixed frequency Peak Current Mode Control, internal compensation, peak-current limit and overtemperature protection. The MCP16311 provides all the active functions for local DC-DC conversion, with fast transient response and accurate regulation.

简介

MCP16312属于集成电路（IC）的稳压器-DC-DC开关稳压器。由制造生产的MCP16312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。
