GENERAL DESCRIPTION
The ADuM60001 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 combi-
nations 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
31% efficiency. The result is a small form factor, total isolation
solution.
Higher output power levels are obtained by using the ADuM6000
to augment the power output of the ADuM5401, ADuM5402,
ADuM5403, ADuM5404, ADuM520x, and ADuM620x 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.
