Description
1500V isolation
OBD dual-output dc-dc converters provide up to 25 watts
of output power in an industry-standard package and
footprint. These units feature excellent efficiency, six-sided
shielding, and fixed switching frequency. With 100°C case
operation, the OBS Series is well suited to telecom,
networking, and industrial applications. The OBD Series is
100% surface-mount construction and fully compatible with
production board washing processes.
