is an isolated dc-to-dc converter based on the
Analog Devices, Inc.,
technology. The dc-to-dc converter
in this device provides regulated, isolated power in several combi-
nations of input and output voltage as listed in Table 1.
The Analog Devices chip-scale transformer
transfers isolated power in this dc-to-dc converter with up to
33% efficiency. The result is a small form factor, total isolation
Higher output power levels are obtained by using the ADuM5000
to augment the power output of
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
application note for board
