GENERAL DESCRIPTION
The EVAL-ADuM3070EBZ demonstrates two separate
applications for the ADuM3070 isolated switch regulator with
integrated feedback. It has two independent power supply
circuits: a double supply and a single supply. The switching
frequency can be set from 200 kHz to 1000 kHz. The board
supports a variety of I/O configurations and multiple trans-
former options. It is equipped with two ADuM3070 isolators.
Footprints for Coilcraft and Halo transformer options
