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 telecom,
networking, and industrial applications, and is fully compatible with production board washing processes.
