Weight:

Screening: Standard only. See Section C2 for screening description.  
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 opera-  
tion 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.  
DESCRIPTION  
HR300 Series™ DC/DC converters combine the small size and high  
reliability of hybrid-based components, the high efficiency of  
switching regulators, and the isolation, regulation, and low noise  
characteristics of linear regulators.  
SMALL SIZE AND RELIABILITY  
HR300 DC/DC converters use thick-film hybrid manufacturing tech-  
niques for smaller size, lighter weight and higher reliability than  
converters produced with other circuit techniques. With a footprint 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.  
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.  
The HR300 parts use the same manufacturing procedures and  
quality controls that Interpoint applies to converters built for aero-  
space and military applications. The converters are hermetically  
sealed in metal packages that are guaranteed a maximum leak rate  
For maximum output regulation, the HR301-2805 is provided with  
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.  
-3  
of less than 10 atm-cc/sec.  
HIGH PERFORMANCE  
HR300 converters use a constant frequency pulse-width modulated  
switching regulator design operating in the forward mode with a  
clock 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 HR301-2805). On dual output models, up to 90% of full power  
is available from either output up to a combined total of 30 watts.  
INHIBIT FUNCTION  
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 acti-  
vate the inhibit function.  
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).
