The HR120 Series™ of DC/DC converters offers up to 12 watts of power from single or dual outputs in a single package over a –40°C to +85°C temperature range. Thick film hybrid manufacturing technology produces high levels of miniaturization, giving the HR120 Series converters a low profile (0.330 inch), small board area (1.65 square inches), and high power density (22 watt/in3). The parts are packaged in sealed steel enclosures, making them ideal for use in high reliability applications. Each unit is guaranteed to pass a hermeticity test with a maximum leak rate of 0.001 atm-cc/sec. description constant output current control with no foldback characteristics. HR120 converters are provided with internal filtering elements on both the input and output to help reduce the need for external components. WiDe Voltage Range Design MethoDology The 5 and 12 volt output models provide full power operation over the input voltage range of 16 to 40 volts (19 to 40 volts for 15 volt output models). Operation below 16 volts (or below 19 volts for the 15 volt output models), including operation in MIL-STD-704E emergency power conditions, is possible with derated output power. Please refer to the low voltage drop-out graphs, Figures 9 and 10. The HR120 Series provides full power operation at case temperatures from –40°C up to +85°C. Depending on operating levels, air flow, and ambient temperature, heat sinking may be required. The HR120 converters are switching regulators which use a quasisquare wave, single ended forward converter design with a nominal switching frequency of 600 kHz. Isolation between input and output circuits is provided with a transformer in the forward power loop and a temperature insensitive optical link in the feedback control loop. Output regulation is accomplished with constant frequency pulse width modulation. Both line and load regulation are typically within 10 mV. On dual output models, the positive output is independently regulated and the negative output is cross-regulated. Figures 7 and 8 illustrate what effects load changes have on the negative output. Indefinite short circuit protection and overload protection are provided by sensing output load current and restricting the output current to approximately 125% of full load output current. Since the output current is sensed in the secondary stage, the result is a predictable, inhibit FeatuRe An inhibit terminal is provided that can be used to disable internal switching, resulting in a very low quiescent input current. An open collector TTL compatible low (≤0.8 V) is required to control the inhibit function. This level may be supplied by an open collector gate since the inhibit pin is provided with an internal pull-up resistor.
