Microchip DC/DC Converter Reference Designs

Microchip Technology introduced the Quarter Brick DC/DC Converter Reference Design and DC/DC LLC Converter Reference Design. The reference designs feature intelligent control of the power converter and serial system communication, remote control and monitoring, and full fault protection. The reference designs are implemented using Microchip’s dsPIC33F GS digital-power Digital Signal Controllers (DSCs), which provide fully digital control of the power-conversion and system-management functions. The DC/DC Reference Designs (software, Gerber files, MATLAB models, Webinars and application notes) can be downloaded for free.
