QES SERIES - 66 WATT
DESCRIPTION
FEATURES
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.
