LED lighting power ICs blend analogue regulation, digital control

March 23, 2016 // By Graham Prophet
Microchip's digitally-enhanced power analogue controllers have been designed for next-generation lighting applications. MCP19116 and MCP19117 enable intelligent, configurable, and accurate LED lighting. Integrating an intelligent PWM controller with a PIC MCU core presents a digital interface to support communication and configuration and remote monitoring/control

MCP19116 and MCP19117 increase accuracy for LED lighting and allow users to carefully control LED light output levels without sacrificing colour or light quality for reliable long-life applications. Efficiency and longevity are drivers in LED adoption. However, light quality remains one of the most important system considerations. Colour, brightness, and controllability are the key to a successful lighting product. By combining the power and performance of an analogue-based controller with the flexibility of a digital interface, the MCP19116/7 is an intelligent pulse width modulation (PWM) controller with a fully integrated PIC MCU core that can deliver cost savings while still providing the highest standards in reliability, efficiency, and light quality. The digital interface also allows for communication and configuration, allowing a subsystem to report status or be remotely controlled. This functionality is necessary for adding lighting to many applications, especially high-reliability automotive and remotely accessible IoT devices.


Microchip also announces the MCP19117 Flyback Evaluation Board (ADM00663), priced at $49.99. This evaluation board is offered with a flyback design supporting constant current loads up to 50V, for driving a medium-voltage LED string.


Also available for the MCP19116 and MCP19117 is Microchip’s full suite of development tool support including MPLAB X Integrated Development Environment (IDE). An MPLAB X plug-in specific to the digitally enhanced power analogue controllers is also available.


The MCP19116 is in a 4 x 4 QFN package, and the MCP19117 in a 5 x 5 QFN package.
