QES single output DC/DC converters provide up to 66
Watts of output power in an industry standard, quarter-
brick package. The QES converters feature open-frame
packaging, along with planar magnetics and a high
efficiency topology to provide maximum useable power
with minimal thermal constraints. The QES is suited to
telecom, networking, and industrial applications, and is
fully compatible with production board washing processes.
