APPLICATIONS
The 5QA-XD & 5QB-XD 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.

Specif cations can be changed any time without notice.
No parallel connection or plug and play.
Note:
1. The load shouldn't be less than 10%, otherwise ripple will increase dramatically.
2. Operation under 10% load will not damage the converter; However, they may not meet all specification listed.
3. All specifications measured at Ta=25°C, humidity<75%, nominal input voltage and rated output load unless
otherwise specified.
4. In this data sheet, all the test methods of indications are based on corporate standards.
