QBS DC/DC Series Data Sheet  
Description  
Features  
• Water Washable  
• Outputs From  
2.5V to 15V  
• 1500V Isolation  
• Positive or Negative  
Enable Logic  
QBS single output DC/DC converters provide up to 120  
watts of output power in an industry-standard,  
quarter-brick footprint. The QBS converters feature  
open-frame packaging, along with planar magnetics to  
provide maximum useable power with minimal thermal  
constraints. The QBS is especially suited to telecom,  
networking, and industrial applications, and is fully  
compatible with production board washing processes.  
• “Quarter-Brick”  
• High Power Density Up  
To 120W  
• Open-Frame Packaging  
• 100°C Baseplate Operation
