MCP19111中文资料Digitally Enhanced Power Analog Buck Controller数据手册Microchip规格书

描述 Description

The MCP19111 is a mid-voltage (4.5-32V) analog-based PWM controller family with an integrated 8-bit PIC® microcontroller.This unique product 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.The MCP1911x family, when combined with Microchip's MCP87xxx MOSFETs, or any low-FOM MOSFET, produce high-efficiency (>96%) DC/DC power-conversion solutions.

特性 Features

• Wide Operating Voltage Range: 4.5-32V
• Integrated 8-Bit PIC® Microcontroller
• I2C Communication Interface
• Integrated Current Sense
• Custom Algorithm Support

简介

MCP19111属于集成电路（IC）的PMIC-稳压器-DCDC开关式控制器。由制造生产的MCP19111DC-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。
