描述 Description

The MCP19114 is a mid-voltage (4.5-42V) analog-based PWM controller with an integrated 8-bit PICTM Microcontroller. This unique product family combines the performance of a high-speed analog solution, including high-efficiency and fast transient response, with the configurability and communication interface of a digital solution. Combining these solution types creates a new family of devices that maximizes the strengths of each technology to create a more cost-effective, configurable, high-performance power conversion solution.Please Note: Our MCP19114 is a smaller, functionally equivalent version of our MCP19115. The MCP19114 and MCP19115?development tools, including both hardware and software tools, provide a convenient and powerful development platform upon which to develop and evaluate your Boost and?Buck/Boost power supply design.

簡介

MCP19114屬于集成電路（IC）的PMIC-穩(wěn)壓器-DCDC開關(guān)式控制器。由制造生產(chǎn)的MCP19114DC-DC 開關(guān)控制器PMIC（電源管理集成電路）DC 到 DC 開關(guān)式控制器是用于高效率電路的穩(wěn)壓 IC，其配置為生成高于（突升或步升）或低于（突降或步降）輸入電源的輸出電源電壓。其他拓?fù)浣Y(jié)構(gòu)可能包括：降壓-升壓、反激、正激、Cuk、SEPIC、全橋、半橋和推挽式。這些器件不同于需要最小電壓并“燒盡”多余電壓的線性穩(wěn)壓器。
