DESCRIPTION
HR300 SeriesDC/DC converters combine small size high reliability hybrid-based components, high efficiency switching regulators, isolation, regulation, noise characteristics linear regulators.
SMALL SIZE RELIABILITY
HR300 DC/DC converters thick-film hybrid manufacturing techniques smaller size, lighter weight higher reliability than converters produced with other circuit techniques. With footprint less than square inches inch height, HR300 converters reach power densities watts cubic inch. HR300 parts same manufacturing procedures quality controls that Interpoint applies converters built aerospace military applications. converters hermetically sealed metal packages that guaranteed maximum leak rate less than 10-3 atm-cc/sec.
Short circuit protection provided through foldback current limiting. When output current reaches approximately 125% full rated load, output voltage begins reduce protect converter. converter sustain true short circuit condition indefinitely. HR300's flanged case facilitates removal heat provides mechanically secure mounting. full power operation indefinite short circuit protection system requirement, HR300 converter should mounted with efficient heat sink contact with mounting flange. Internal filters HR300 converters provide noise both input outputs. HR301 models, two-section filters limit output ripple voltage reflected input ripple current. HR302 models, single-section filters perform same function. maximum output regulation, HR301-2805 provided with external output voltage remote sense pins. Connecting remote sense pins load provides four-terminal voltage mode which eliminates adverse effects line resistance voltage drops. Remote sense pins left unconnected, cautions this data sheet. normal operation, remote sense pins should connected respective output pins.
HIGH PERFORMANCE
HR300 converters constant frequency pulse-width modulated switching regulator design operating forward mode with clock switching frequency kHz. Isolation achieved through transformer forward power circuit optocoupler feedback control loop. full load output power watts available over entire input range HR301-2805). dual output models, full power available from either output combined total watts. HR300's high efficiency maintained over entire input voltage range from approximately full load full load (see typical efficiency curves).
INHIBIT FUNCTION
inhibit provided allow logic input shut down converter. open circuit inhibit (pin allows normal operation. connection between inhibit input common (pin disables internal oscillator, shutting down output. inhibit open circuit voltage single output models, HR302-2812 HR302-2815. inhibit mode, approximately must sunk from inhibit pin. active open collector required activate inhibit function.
