The MCP19117 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. These products allow the development of flexible power supplies that can be configured perfectly to the target application with minimal external components. In addition, these devices can be programmed to dynamically respond to measurements or events within the system, dynamically tailoring the operation to the environment, or intelligently responding to faults for robust operation.
This device is similar to the MCP19114 and MCP19115, but contains additional calibration features for improved accuracy and measurement, as well as a larger flash memory for storing additional code within the device. The MCP19117 is functionally equivalent to our MCP19116, however the MCP19117 offers more GPIO and a debugging interface. The MCP19116 and MCP19117 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.
The MPLAB® PM3 Universal Device Programmer is easy to use and operates with a PC or as a stand-alone unit, and programs Microchip's entire line of PIC® devices as well as the latest dsPIC® DSC devices. When used standalone, data can be loaded and saved with the SD/MMC card (not included).
The MCP19117-Flyback Standalone Evaluation Board and Graphical User Interface (GUI) demonstrate the MCP19117 performance in a synchronous Flyback topology. It is configured to regulate load current, and is well suited to drive LED loads. Nearly all operational and control system parameters are programmable through the integrated PIC MCU core. The MCP19117 evaluation board comes preprogrammed with...
