DESCRIPTION

FEATURES

OBS SERIES

25 WATT

OBS single output DC/DC converters provide up to 25 Watts of output power in an industry standard package and footprint. The OBS units feature excellent efficiency, sixsided shielding, and fixed switching frequency. With 100°C case operation, the OBS converters are especially suited to telecom, networking, and industrial applications. These units are 100% surface-mount construction and fully compatible with production board washing processes.

• Industry standard package

• 24 and 48V input versions

• 25W output power

• 100°C baseplate operation
