Digitally-Enhanced Power Analog Controllers for LED Lighting

Microchip Technology Inc. today announced two new digitally-enhanced power analog controllers designed for LED lighting applications. The MCP19116 and MCP19117 increase accuracy for LED lighting and allow users to carefully control LED light output levels without sacrificing color or light quality for reliable long-life applications.

Efficiency and longevity have consistently been drivers in LED adoption. However, light quality remains one of the most important system considerations. Color, brightness, and controllability are the key to a successful lighting product. By combining the power and performance of an analog-based controller with the flexibility of a digital interface, the MCP19116/7 is an intelligent 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 internet of things (IoT) devices.

“The MCP19116/7 is designed to create excellent LED lighting applications, and can do so better than any other LED drive IC on the market,” said Keith Pazul, senior manager of Microchip’s Analog Power and Interface Division. “Many companies claim they have tight current regulation accuracy in their controllers, when in reality they ignore various sources of error from other components in the system. These devices are highly accurate across all operating conditions and adjustable on the fly using the integrated PIC MCU core. This is truly a best in class solution.”

“LED is here to stay,” continued Pazul. “Microchip has made a diverse investment in technologies to control and drive future generations of LED lighting products. We are proud to be a premier supplier of lighting solutions to a wide variety of applications and end markets.”

Microchip’s MCP19117 Flyback Evaluation Board (ADM00663, $49.99), also announced today, is available now. This evaluation board is offered with a flyback design supporting constant current loads up to 50V, suited 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). A MPLAB X plugin specific to the digitally-enhanced power analog controllers is available.

The MCP19116 is available now for sample and volume production in 4 x 4 QFN packages for $2.83 each, in 10,000-unit quantities. The MCP19117 is available now for sample and volume production in 5 x 5 QFN packages for $3.00 each, in 10,000-unit quantities.
