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
