DESCRIPTION
HR700 Series DC/DC converters offer watts power from single, dual, triple outputs package. converters combine small size high reliability hybrid-based components, high efficiency switching regulators, isolation, regulation, noise characteristics linear regulators.
provided detecting peak primary switching current cycle basis limiting approximately 130% full load input current. This method results quick positive current limiting under short circuit conditions. HR700 Series DC/DC converters designed provide full power operation over input voltage range VDC. Operation below input volts possible with derated output power. Outputs available single, dual triple outputs. converters typically provide greater than efficiency over entire input range. Line regulation typically within 0.1% load regulation within 0.2%.
SMALL SIZE
HR700 converters manufactured using techniques that provide very small size profile components. Each converter uses less than eight square inches board areas 0.595 inches high less. overall power density watts cubic inch.
NOISE
HR700 Series converters offer noise both input output lines. section, four pole, input filter included provide very reflected line ripple current. Output ripple maintained less than single dual models triple output models.
HIGH RELIABILITY
Assembled using thick-film technology, HR700 parts same manufacturing procedures quality controls that apply converters designed commercial airliners, space shuttle, advanced fighter aircraft, other high reliability applications. steel cases hermetically sealed nitrogen environment guaranteed maximum leak rate less than 10-3 atmcc/sec. devices 100% electrically tested.
INHIBIT/SYNC FEATURE
inhibit/sync standard models HR700 Series converters. serves both output inhibit synchronization input. inhibit mode open collector compatible (<0.8 will disable internal switching thereby inhibiting unit's output. Inhibiting this manner results extremely quiescent current.
HIGH PERFORMANCE
HR700 series parts high efficiency, noise, pulse-width modulated converters which quasi-square wave forward converter design with nominal switching frequency kHz. Isolation between input output provided with transformer forward power loop wide band, temperature insensitive, optical link feedback control loop. Short circuit protection

THERMAL MANAGEMENT HEAT SINK RECOMMENDATIONS
HR700 Series converter still (other than convective currents) with conductive cooling paths other than through electrical connections pins will exhibit thermal resistance approximately watt. cases where this value proves high recommended that additional heat sinking supplied. simplest method accomplishing this firmly attach converter thereby providing conductive thermal path. Secondly recommended that airflow provided over converter. Although each situation requires thorough thermal analysis these measures reduce thermal resistance watt. calculations indicate further heat sinking required recommended that additional thermal mass provided either under base plate converter's mounting flanges both.
CALCULATING MAXIMUM AMBIENT TEMPERATURE
HR700 Series DC/DC converters upper operating temperature 85°C baseplate case. degree heat sinking required remain within this limit determined from Figure which shows maximum allowed internal power dissipation (PDISS ambient temperature various heat sink thermal resistances. PDISS calculated PDISS POUT efficiency POUT efficiency combinations POUT various models obtained from graphs preceding pages. Example: Converter HR702-2815, TAMB 70°C, VDC, POUT watts Efficiency (From Figure PDISS 7.95 watts From Figure that this situation will require thermal resistance approximately 4.5°C watt. Conversely also find maximum ambient temperature which tolerated know heat sink thermal resistance. Example: Converter HR701-2805, VDC, POUT Thermal Resistance watt. Efficiency 83.5% (From Figure PDISS 0.835) 8.89 watts. From Figure that maximum allowed ambient temperature approximately 75°C.
