In this lighting application the dsPIC SMPS device is performing multiple functions in the LED lighting module replacing multiple devices with a single digital controller. The dsPIC implements the DC to DC converter for getting the proper voltage level, the ballast function to precisely control the current, the communication and control link, and it enables advanced dimming and color control features. End applications include architectural lighting, pool and spa lighting, and automotive lighting.
Microchip enables the benefits of digital lighting with the dsPIC SMPS and Digital Power Conversion family of devices. These devices include peripherals designed specifically for power conversion applications such as 1 nanosecond resolution Pulse Width Modulators (PWM), 4 MSPS Analog to Digital Converters (ADC), and on chip high speed Analog Comparators with integrated programmable reference voltages.
