6 Summary

This application note outlines the tradeoffs between controller and converter designs. New 65V and 80V converters integrate innovation on the fronts of packaging, FET technology, IC design and manufacturing. These new converters give power designers a new option in their tool belt that enable smaller, lower EMI and easy to design power-stages that are scalable to output currents only controllers could touch in the past. However, controllers won’t be going away anytime soon with their design flexibility and optimization. As with all great challenges there are always multiple designs with tradeoffs.

The DC/DC converters and controllers in Table 6-1 are ideal for 24V systems and 48V systems across applications. For further design size reduction, greater ease of use and lower EMI, an integrated inductor module may be of interest such as TPSM365R6 and TPSM5601R5H.
