Product Details
The ADuM520x are dual channel digital isolators with isoPower, an integrated, isolated dc-to-dc converter. Based on the Analog Devices, Inc., iCoupler® technology, the dc-to-dc converter provides up to 500 mW of regulated, isolated power with 5.0 V input and 5.0 V output voltage, or 200 mW of power with 3.3 V input and 3.3 V output voltage. This eliminates the need for a separate isolated dc-to-dc converter in low power isolated designs. The Analog Devices chip scale transformer iCoupler technology is used for the isolation of the logic signals as well as for the dc-to-dc converter. The result is a small form factor, total isolation solution.
ADuM520x units may be used in combination with ADuM5401, ADuM5402, ADuM5403, ADuM5404 and ADuM5000 with isoPower® to achieve higher output power levels and greater channel counts (see the Increasing Available Power section).
The ADuM520x isolators provide two independent isolation channels in a variety of channel configurations and data rates (see the Ordering Guide for options).
isoPower uses high frequency switching elements to transfer power through its transformer. Special care must be taken during printed circuit board (PCB) layout to meet emissions standards. Refer to the AN-0971 application note for details on board layout recommendations.
