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.
