DESCRIPTION
HR120 Seriesof DC/DC converters offers watts power from single dual outputs single package over -40°C +85°C temperature range. Thick film hybrid manufacturing technology produces high levels miniaturization, giving HR120 Series converters profile (0.330 inch), small board area (1.65 square inches), high power density watt/in3). parts packaged sealed steel enclosures, making them ideal high reliability applications. Each unit guaranteed pass hermeticity test with maximum leak rate 0.001 atmcc/sec. Indefinite short circuit protection overload protection provided sensing output load current restricting output current approximately 125% full load output current. Since output current sensed secondary stage, result predictable, constant output current control with foldback characteristics. HR120 converters provided with internal filtering elements both input output help reduce need external components.
WIDE VOLTAGE RANGE
volt output models provide full power operation over input voltage range volts volts volt output models). Operation below volts below volts volt output models), including operation MIL-STD-704E emergency power conditions, possible with derated output power. Please refer voltage drop-out graphs, Figures HR120 Series provides full power operation case temperatures from -40°C +85°C. Depending operating levels, flow, ambient temperature, heat sinking required.
DESIGN METHODOLOGY
HR120 converters switching regulators which quasisquare wave, single ended forward converter design with nominal switching frequency kHz. Isolation between input output circuits provided with transformer forward power loop temperature insensitive optical link feedback control loop. Output regulation accomplished with constant frequency pulse width modulation. Both line load regulation typically within dual output models, positive output independently regulated negative output cross-regulated. Figures illustrate what effects load changes have negative output.
INHIBIT FEATURE
inhibit terminal provided that used disable internal switching, resulting very quiescent input current. open collector compatible (0.8 required control inhibit function. This level supplied open collector gate since inhibit provided with internal pull-up resistor.
