APPLICATIONS
The B-XD-1W5 series
is a family of cost
effective 1.5W single output DC/DC converters.
These converters are in an ultra miniature DIP8
case. Devices are encapsulated. High performance
features: 1000VDC input/output isolation, high
efficiency operation, output voltage accuracy of
±3%
maximum, input range of
±10%
tolerance
and low output ripple and noise.

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.
