Is there a comparable device to the ADUM6000, but with higher efficiency? The ADUM6000 has up to 31% efficiency.
There is not another device that I know of that meets the features that the ADuM6000 has: small size, isolated dc to dc converter with 5000V rms isolation. The ADuM4070 has a higher efficiency of 70 -80% and meets the 5000Vrms isolation, but has a larger size solution. This solution requires an external transformer, diode and coil.The transformer vendors are Coilcraft and Halo, and for 5000V isolation the Halo is much smaller.
