Microchip Technology Inc. announced two new digitally controlled DC/DC converter reference designs with advanced, high-efficiency topologies to help designers optimize contrasting requirements in the design process, including efficiency, power density and cost.
Both the quarter brick DC/DC reference design and the DC/DC LLC converter reference design use Microchip’s 16-bit dsPIC33F GS series of digital-power digital signal controllers (video overview below ) for fully digital control of the power-conversion and system-management functions.
