QES050YE Datasheet | Power One

DESCRIPTION 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 tele, networking, and industrial applications, and is fully patible with production board washing processes.
