ADuM6028 Functional Block Diagram Industrial PLCs GENERAL DESCRIPTION 1 The ADuM6020 and ADuM6028 are isoPower, integrated, The ADuM6020 and ADuM6028 isolated dc-to-dc converters isolated dc-to-dc converters. Based on the Analog Devices, Inc., provide two different package variants: the ADuM6020 in a iCoupler technology, these dc-to-dc converters provide wide body, 16-lead SOIC IC package, and the ADuM6028 in regulated, isolated power that is below CISPR22 Class B limits at the space saving, 8-lead, wide body SOIC IC package. For 5 V full load on a 2-layer printed circuit board (PCB) with ferrites. input operations, use the ADuM6020-5BRWZ and the Common voltage combinations and the associated current ADuM6028-5BRIZ. For 3.3 V input to 3.3 V output operations, output levels are shown in Table 1 through Table 4. use the ADuM6020-3BRWZ and the ADuM6028-3BRIZ. See the Pin Configuration and Function Descriptions section and The ADuM6020 and ADuM6028 eliminate the need to design the Ordering Guide for more information. and build isolated dc-to-dc converters in applications up to 500 mW. The iCoupler chip scale transformer technology is used for the magnetic components of the dc-to-dc converter. The result is a small form factor, isolated solution. 1 Protected by U.S. Patents 5,952,849 6,873,065 6,903,578 and 7,075,329. Other patents are pending. Rev.
