Product Details

The ADuM5020 is an isoPower^®, integrated, isolated dc-to-dc converter. Based on the Analog Devices, Inc., iCoupler^® technology, the dc-to-dc converter provides regulated, isolated power that is below CISPR22 Class B limits at full load on a 2-layer printed circuit board (PCB) with ferrites.

The ADuM5020 eliminates the need to design and build an isolated dc-to-dc converter in 500 mW applications. 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 ADuM5020 isolated dc-to-dc converter is available in a wide-body 16-lead SOIC package.

Applications

RS-485/RS-422/CAN transceiver power
Power supply startup bias and gate drives
Isolated sensor interfaces
Industrial PLCs

View Detailed Evaluation Kit Information

The EVAL-ADUM5020EBZ allows the user to evaluate the ADuM5020 isolated power solution. The ADuM5020 eliminates the need to design and build an isolated dc-to-dc converter in 500 mW 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 ADuM5020 dc-to-dc converter provides regulated, isolated power that is well below CISPR22/EN55022 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 ADuM5020 or ADuM6020 can be found in the ADuM5020 or ADuM6020 data sheet, available from Analog Devices, Inc., and must be consulted in conjunction with this user guide when using the evaluation board.
