OWS SERIES - 25 WATT

DESCRIPTION

FEATURES

OWS single output DC/DC converters provide up to

25 Watts of output power in an industry standard

package and footprint. The OWS features excellent

efficiency, six-sided shielding, and a fixed switching

frequency. With 85°C case operation, the OWS is

especially suited to telecom, networking, and

industrial applications.
