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.
