A series of DC-DC converters are designed for harsh and extreme environments requiring reliable operation in high temperatures.
VPT Inc., Albuquerque, N.M., released the HTD isolated 1.5 W DC-DC converter, which operates from -67 to 311°F (-55 to 155°C). HTD non-isolated DC-DC converters operate from -67 to 365°F (-55 to 185°C). Within their design, component-attach and die bonding are optimized for high temperature life, and hermetic metal packaging protects internal components for long-term reliability. The converters, which have dual outputs, are suited for downhole oil and gas, MWD/LWD and wireline logging tools, aircraft engine electronics and other industrial applications.
