Description
The IR & SIR series are isolated/regulated DC-DC converters with wide input range and tight regulation specifications. These modules have trimming and control features. Single and dual isolated output models are standard. They can operate up to 10W over the temperature range of -25°C to +70°C without derating, a heat sink or active cooling.
