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 Microchipís 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.
Quarter Brick DC/DC Converter Reference Design:
- Quarter Brick Size
- Phase Shift Full Bridge (PSFB) Topology
- 200W Output Power
- Input voltage 36-76 Vdc; output voltage 12V
- >93% efficiency
DC/DC LLC Converter Reference Design:
- LLC resonant topology
- 200W output power
- Input voltage 350-420 Vdc; output voltage 12V
- >95% efficiency
