Powerful solutions for DC/DC conversion

Powerful solutions
for DC/DC conversion
For DC/DC conversion, NXP offers a wide range of solutions that simplify design, improve performance, and lower the
overall cost. From fast-switching MOSFETs to highly integrated power trains, we pack more power into a smaller space
while keeping things cool. We design for all kinds of applications – from mobile communications and high-end servers to
domestic and automotive applications – with special emphasis on high-density applications like half-bridge
and forward-topology DC/DC convters. To improve power density, we specialize in small-footprint packages with superb
thermal properties. Our LFPAK and nanoPAK options increase supply efficiency and improve heat dissipation, bringing
thermally superior operation to the TSOP6 and SO8 footprint. That means smaller, more efficient designs or improved
performance in the same space.
