DESCRIPTION
HR700 Series DC/DC converters offer up to 70 watts of power from
single, dual, or triple outputs in one package. The converters
combine the small size and high reliability of hybrid-based compo-
nents, the high efficiency of switching regulators, and the isolation,
regulation, and low noise characteristics of linear regulators.
provided by detecting peak primary switching current on a cycle
basis and limiting it to approximately 130% of the full load input
current. This method results in quick and positive current limiting
under short circuit conditions.
HR700 Series DC/DC converters are designed to provide full power
operation over the input voltage range of 19 to 40 VDC. Operation
below an input of 19 volts is possible with derated output power.
Outputs are available as 5, 12, and 15 VDC single, dual and triple
outputs. The converters typically provide greater than 80% effi-
ciency over the entire input range. Line regulation is typically within
0.1% and load regulation within 0.2%.
SMALL SIZE
The HR700 converters are manufactured using techniques that
provide very small size and low profile components. Each converter
uses less than eight square inches of board areas and is 0.595
inches high or less. The overall power density is 20 watts per cubic
inch.
LOW NOISE
The HR700 Series converters offer low noise on both the input and
output lines. A two section, four pole, LC input filter is included to
provide very low reflected line ripple current. Output ripple is main-
tained at less than 50 mV p-p for single and dual models and 85 mV
p-p for triple output models.
HIGH RELIABILITY
Assembled using thick-film technology, the HR700 parts use the
same manufacturing procedures and quality controls that we apply
to converters designed for commercial airliners, the space shuttle,
advanced fighter aircraft, and other high reliability applications. The
steel cases are hermetically sealed in a dry nitrogen environment
and are guaranteed a maximum leak rate of less than 10
-3
atm-
cc/sec. All devices are 100% electrically tested.
INHIBIT
/
SYNC FEATURE
An inhibit/sync pin is standard on all models of the HR700 Series
converters. The pin serves as both an output inhibit and as a
synchronization input. In the inhibit mode an open collector TTL
compatible low (<0.8 V) will disable internal switching thereby
inhibiting the unit’s output. Inhibiting in this manner results in an
extremely low quiescent current.
HIGH PERFORMANCE
The HR700 series parts are high efficiency, low noise, pulse-width
modulated converters which use a quasi-square wave forward
converter design with a nominal switching frequency of 245 kHz.
Isolation between input an output is provided with a transformer in
the forward power loop and a wide band, temperature insensitive,
optical link in the feedback control loop. Short circuit protection is
B4-33
