OBD SERIES - DUAL OUTPUT, 25 WATT
DESCRIPTION
FEATURES
• Trim and Enable Pins
• 6-Sided Shielding
• 1500V Isolation
OBD dual output DC/DC converters provide up to 25 watts • Industry Standard Package
of output power in an industry standard package and • 48V Input
footprint. These units feature excellent efficiency, six-sided • Fixed-Frequency Design
shielding, and fixed switching frequency. With 100°C case • 100°C Case Operation
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.
