DC/DC，步降1.8V5V ~ 12V

Overview

The MCP19111 is a Digitally Enhanced Power Analogue Controller with Integrated Synchronous Driver. It combines a pure-analogue PWM controller with a supervisory microcontroller making it a fast, cost-effective, and configurable power conversion solution. The MCP19111 is ideal for standard power conversion, LED drivers, and battery charging applications.The MCP19111 Evaluation Board demonstrates how the MCP19111 device operates in a synchronous buck topology over a wide input voltage and load range. Nearly all operational and control system parameters are programmable by utilising the integrated PIC microcontroller core. MPLAB X IDE can be used in conjunction with a Graphical User Interface (GUI) plug-in to easily configure the MCP19111. Alternatively, the user can program the MCP19111 using their own firmware, tailoring it to their application. The evaluation board contains headers for ICSP™ (In-Circuit Serial Programming™) as well as I²C communication, pull-up and pull-down resistor pads and test point pads on each GPIO pin, and two push buttons for system development.

Voltage input range: 5V to 12VAdjustable Vout range: 0.5V to 3.6VMaximum output current: 30A with proper air flowProgramming and I²C communication headersFactory programmed to produce 1.8V from 12V sourceThe factory programmed source code is available
