Non- screened versions of the HTA converters are available for system development purposes. Variations in electrical specifications and screening to meet custom requirements can be accommodated. Applications n Down Hole Exploration Tools The HTA Series of DC-DC converters is a family of 20W, single and dual output, high reliability devices designed to operate in extremely high temperature environments such as those encountered in oil exploration applications. Features include small size, low weight and high tolerance to environmental stresses such as wide temperature extremes, severe shock and vibration. All internal components are derated to meet the intended operating environment. Documentation including electrical stress and thermal analysis are available. The converters incorporate a fixed frequency single forward topology with magnetic feedback and internal EMI filter. All models include an external inhibit port and have an adjustable output voltage. They are enclosed in a hermetic 3.805" x 1.5" x 0.430" AlSi package and weigh less than 70grams. The package utilizes rugged ceramic feed-thru copper core pins and is sealed using parallel seam welding. 07/30/10 The HTA series of converters utilize a single-ended forward topology with resonant reset. The nominal switching frequency is 500KHz. Electrical isolation and tight output regulation are achieved through the use of a magnetically coupled feedback. Output current is limited under any load fault condition to approximately 125% of rated load at maximum operating case temperature. An overload condition causes the converter output to behave like a constant current source with the output voltage dropping below nominal. The converter will resume normal operation when the load current is reduced below the current limit point. This protects the converter from both overload and short circuit conditions. The current limit point exhibits a slightly negative temperature coefficient to reduce the possibility of thermal runaway. An external Inhibit port is provided to control converter operation. The converter’s operation is inhibited when this pin is pulled low. It is designed to be driven by an open collector logic device. The pin may be left open for normal operation and has a nominal open circuit voltage of 4.0V with respect to the Input Return (pin 2). The output voltage of all models can be adjusted using a single external resistor. Circuit Description PD-97309B |
