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
