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.
