APPLICATIONS
The A-XD-1W25 & B-XD-1W25 series of
DC/DC converters is particularly suited to
isolating and/or converting DC power rails.
The galvanic isolation allows the device to be
configured to provide an isolated negative rail
in systems where only positive rails exist. The
wide temperature range guarantees startup
from -40°C and full 1.25 watt output at 85°C.
For lower ripple,refer to output ripple reduction
section.
All specif cations typical at TA=25 ° C, nominal input voltage and rated output current unless otherwise specif ed.
