GENERAL DESCRIPTION ADUM5000ARWZ

The ADuM50001 is an isolated dc-to-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 voltages 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.
