Figure 3. ADuM5201 Based on the Analog Devices, Inc., iCoupler technology, the dc-to-dc converter provides up to 500 mW of regulated, isolated power at either 5.0 V or 3.3 V from a 5.0 V input supply, or 3.3 V V V OA IA 3 14 from a 3.3 V supply at the power levels shown in Table 1. These ADuM5202 devices eliminate the need for a separate, isolated dc-to-dc converter V V OB IB 4 13 in low power isolated designs. The iCoupler chip scale transformer technology is used to isolate the logic signals and for the magnetic Figure 4. ADuM5202 components of the dc-to-dc converter. The result is a small form factor, total isolation solution. The ADuM5200/ADuM5201/ADuM5202 isolators provide two Table 1.

Special care must be taken during printed circuit board (PCB) layout to meet emissions standards.
