ALBUQUERQUE, N.M., 10 May 2016. VPT Inc. (VPT), a HEICO company (NYSE:HEI), is introducing the HTD Series of DC-DC converters at HiTEC 2016, the iMAPS International Conference on High Temperature Electronics. The HTD Series of DC-DC converters, leveraging VPT’s high-reliability power supply design heritage, is specifically designed for harsh and extreme temperature environments, including aircraft engine electronics and other industrial applications requiring reliable operation in high temperatures.

The HTD isolated 1.5 watt DC-DC converter operates from -55°C to 155°C and the HTD non-isolated DC-DC converters operate from -55°C to 185°C. Each model has dual outputs and is designed using thick film hybrid microcircuit technology, bare semiconductor die integrated with passive components, and thick film conductors on a ceramic substrate. Within the HTD design, component-attach and die bonding are optimized for high temperature life, and hermetic metal packaging protects internal components for long-term reliability.

“We developed these products specifically for reliable performance in settings which are both high-temperature and rugged, testing them extensively for operating life and temperature cycling over the full temperature range as well as for mechanical shock and vibration,” VPT’s Director of Advanced Product Development Steve Butler says.

Each HTD Series product has a low profile of 0.27” and measures less than an inch wide at 0.975” x 0.800”.

“Electronics for downhole and near-engine applications must operate consistently within brutal environments,” says Vice President of Sales & Marketing Monty Pyle. “With VPT’s expertise in power supplies for space, avionics and rugged military applications, developing products for these high-temperature applications is a natural extension of our high reliability product lines.”

The HTD Series of DC-DC converters are available for immediate sale. Unit pricing begins at $700-800 (USD) for volume quantities, depending on product model. Custom versions are also available. Additional information on the HTD Series and specific product datasheets can be found at www.vptpower.com.
