HTH27022S

PD-97815 HIGH RELIABILITY DC-DC CONVERTER HTH27022S 165°C, 270V Input, 55W, 22V Single Output Description The HTH27022S is a single output 55W DC-DC converter designed to operate in extremely high temperature environments such as those encountered in oil exploration. Features include small size, low weight and high tolerance to environmental stresses such as wide wide temperature extremes, severe shock and vibration. All internal components and assembly processes have been selected and developed to ensure reliable performance in the intended operating environments. The converter incorporates a fixed frequency forward topology with magnetic feedback and internal EMI filter. It also includes an external inhibit port and have an adjustable output voltage. It is enclosed in a hermetic 4.0" x 2.15" x 0.40" (3.5"x1.5"x0.40"H excluding mounting tabs and I/O pins) AlSi package and weighs less than 70 grams. The package utilizes rugged ceramic feed-thru, copper-cored pins and is sealed using laser welding. Full environmental screening includes temperature cycling, constant acceleration, fine and gross leak, and burn-in. Please refer to Device Screening table.
