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
