Description
The B & SB series are unregulated DC-DC converters in an ultra-miniature encapsulated package – 1.12″ x 0.7″ footprint and low profile – 0.3″. Over 180 models are available in both single and dual outputs. They can operate over the temperature range of -25°C to +70°C without derating, a heat sink or active cooling.
