HR300 DC/DC converters use thick-film hybrid manufacturing techniques for smaller size, lighter weight and higher reliability than converters produced with other circuit echniques. With a footprint t of less than 3.7 square inches and a 0.5 inch height, the HR300 converters reach power densities up to 22 watts per cubic inch. The HR300 parts use the same manufacturing procedures and quality controls that Interpoint applies to converters built for aerospace and military applications. The converters are hermetically sealed in metal packages that are guaranteed a maximum leak rate of less than 10-3 atm-cc/sec. HR300 converters use a constant frequency pulse-width modulated switching regulator design operating in the orward mode with a clock f switching frequency of 240 to 300 kHz. Isolation is achieved through the use of a transformer in the forward power circuit and an optocoupler in the feedback control loop. The full load output power of 30 watts is available over the entire 18 to 36 VDC input range (19 to 36 HR3012805). On dual output models, up to 90% of full power is available from either output up to a combined total of 30 watts. The HR300’s high efficiency is maintained over the entire input voltage range and from approximately 25% of full load to full load (see typical efficiency curves). Small Size and Reliability Short circuit protection is provided through foldback current limiting. When the output current reaches approximately 125% of the full rated load, the output voltage begins to reduce to protect the converter. The converter can sustain a true short circuit condition indefinitely. The HR300’s flanged case facilitates removal of heat and provides for mechanically secure mounting. If full power operation or indefinite short circuit protection is a system requirement, the HR300 converter should be mounted with an efficient heat sink in contact with the mounting flange. Internal filters in all HR300 converters provide low noise on both the input and outputs. On HR301 models, two-section L-C filters limit output ripple voltage and reflected input ripple current. On HR302 models, single-section L-C filters perform the same function. For maximum output regulation, the HR301-2805 is rovided with p external output voltage remote sense pins. Connecting the remote sense pins to the load provides a four-terminal voltage mode which eliminates the adverse effects of line resistance voltage drops. Remote sense pins may be left unconnected, but see cautions in this data sheet. For normal operation, remote sense pins should be connected to the respective output pins. An inhibit is provided to allow a logic input to shut down the converter. An open circuit on the inhibit pin (pin 2 or 8) allows normal operation. A connection between the inhibit pin and the input common (pin 10) disables the internal oscillator, shutting down the output. The inhibit pin has an open circuit voltage of 11 to 16 V on single output models, 8 to 12 V on HR302-2812 and 10 to 14 V on HR302-2815. In the inhibit mode, approximately 1 mA must be sunk from the inhibit pin. An active low open collector is required to activate the inhibit function.
