APPLICATIONS
The B-XD 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

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.
