GENERAL DESCRIPTION

The ADuM6020/ADuM60281 are isoPower®, integrated, isolated

dc-to-dc converters. Based on the Analog Devices, Inc., iCoupler®

technology, these dc-to-dc converters provide regulated, isolated

power that is below CISPR22 Class B limits at full load on a

2‑layer printed circuit board (PCB) with ferrites. Common voltage

combinations and the associated current output levels are shown in

Table 1 through Table 4.

The ADuM6020/ADuM6028 eliminate the need to design 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.

The ADuM6020/ADuM6028 isolated dc-to-dc converters provide

two different package variants: the ADuM6020 in a wide-body,

16-lead SOIC_IC package, and the ADuM6028 in the space-saving,

8-lead, wide-body SOIC_IC package. For 5 V input operations,

use the ADuM6020-5BRIZ and the ADuM6028-5BRIZ. For 3.3 V

input to 3.3 V output operations, use the ADuM6020-3BRIZ and

the ADuM6028-3BRIZ. See the Pin Configuration and Function

Descriptions section and the Ordering Guide for more information.
