The HTA family of high temperature DC-DC converters is designed for high power subsurface applications up to 185°C including down-hole drilling, seismic and natural resource exploration equipment.

The new DC-DC converters are well suited as building blocks and intermediate bus converters for power systems. Available as commercial off-the-shelf (COTS), the new converters significantly reduce design cycles and design costs associated with high temperature industries.

The HTA series not only provides designers with immediate high reliability and design simplification, these devices establish the design foundation and assembly processes for power converters operating in extreme high temperature environments.

The HTA Series is capable of providing up to 20W of output power over extreme case temperatures of minus 35°C to 185°C. The family of devices has an input voltage range of 150V to 250V and is offered in single and dual output configurations. Input and output are galvanically isolated to protect the output loads from catastrophic system failures at the input side and to provide the flexibility of stacking several converters to achieve a higher output voltage.

Additional features include small size, low weight and high tolerance to environmental stresses such as wide temperature extremes and severe shock and vibration. Moreover, electrical stress, thermal analysis and environmental qualification test reports have been completed and are available per request. Please contact IR Santa Clara for custom requirements.
