GENERAL DESCRIPTION
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.
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.
