GENERAL DESCRIPTION
The EVAL-ADUM5028EBZ allows the user to evaluate the
ADuM5028
isolated power solution. The
the need to design and build an isolated dc-to-dc converter in
60 mA applications. The iCoupler® chip scale transformer
technology is used for the inductive component of the dc-to-dc
converter. The result is a small form factor, isolated solution.
Based on the Analog Devices, Inc., iCoupler technology, the
ADuM5028
dc-to-dc converter provides regulated, isolated
power that is well below CISPR22 Class B limits when at full
load on a 2-layer printed circuit board (PCB) with ferrites.
Available supply voltages and the associated output current
levels are shown in Table 1.
Full specifications of the
ADuM5028
ADuM5028
data sheets available from Analog Devices, and
must be consulted in conjunction with this user guide when
using the evaluation board.
