Description

The E & SE series are unregulated DC-DC converters in an ultra-miniature encapsulated package – 1.43″ x 1.24″ (single) or 2″ x 1.12″ (dual) footprint and low profile – 0.4″. 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.
