ADuM6402 ADuM6404 are quad-channel digital isolators with isoPower, V V an integrated, isolated dc-to-dc converter. Based on the Analog IA OA 3 14 V V Devices, Inc., iCoupler technology, the dc-to-dc converter provides OB IB 4 13 V ADuM6403 V OC IC up to 400 mW of regulated, isolated power at either 5.0 V or 3.3 V 5 12 V V OD ID from a 5.0 V input supply, or at 3.3 V from a 3.3 V supply at the 6 11 power levels shown in Table 1. These devices eliminate the need Figure 5.
