Isolated DC/DC Converter

The ADuM5000 is an isolated DC/DC converter based on the Analog Devices, Inc., iCoupler® technology. The dc-to-dc converter in this device provides regulated, isolated power in several combinations of input and output voltage as listed in Table 1.

The Analog Devices chip-scale transformer iCoupler technology transfers isolated power in this dc-to-dc converter with up to 33% efficiency. The result is a small form factor, total isolation solution.

Higher output power levels are obtained by using the ADuM5000 to augment the power output of ADuM5401, ADuM5402, ADuM5403, ADuM5404, ADuM520x , and other ADuM5000 iCouplers with isoPower®.

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. See the AN-0971 application note for board layout recommendations.
