Binning, temperature, component aging, dimming and constant-current drive needs influence light quality and affect the customer experience. In addition to efficiency benefits or lifetime monetary savings, consumers are looking for better interior designs, brighter headlights, more beautiful colors and finer dimming control. To implement proper color, temperature and chromaticity and make better LED and traditional lighting circuits in your application, start with a Microchip evaluation board or reference design.
These designs can be implemented as stand-alone systems using a traditional dimmer and AC input, or as connected systems supporting standard or custom communication protocols to offer new control options.
The MCP19215 Dual Boost/SEPIC Evaluation Board demonstrates how the MCP19215 device operates in boost and SEPIC topologies over a wide input voltage and load range. Nearly all operational and control system parameters are programmable by utilizing the integrated PIC® microcontroller.
The MCP19114 Flyback Stand-Alone Evaluation Board and Graphical User Interface (GUI) demonstrate the MCP19114’s performance in a synchronous Flyback topology. It is configured to regulate load current and is well suited to drive LED loads.
This application note describes a circuit developed as a LED driver solution for automotive applications.
