Description
The A & SM series are unregulated DC-DC converters in an ultra-miniature encapsulated package – 0.500″ x 0.500″ footprint. Over 200 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.
