2、uM3070EBZ 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 co

3、nfigurations and multiple trans-former options. It is equipped with two ADuM3070 isolators.Two independent and isolated circuits comprise the ADuM3070 evaluation board. The single supply is configured as a 5 V secondary isolated supply with a 5 V primary input supply, which can provide up to 2.5 W o

4、f regulated, isolated power. It can be reconfigured for a 3.3 V secondary isolated supply with a 5 V or 3.3 V primary input supply (see the Other Input and Isolated Output Supply Options section).The EVAL-ADuM3070EBZ supports multiple transformer options. The single supply is equipped with a Halo TGSAD-260V6LF (T1) or a Coilcraft JA4631-BL (T2) 1:2 turns ratio transformer. The Coilcraft footprint is offset to the left of the Halo footprint. Figure 5 and Figure 7 show the efficiency curves for the single supply operating with a Coilcraft and a Halo t
