HYBRID - HIGH RELIABILITY
RADIATION HARDENED
DC-DC CONVERTERS
Description
The ARH Series of DC-DC converters has been
designed specifically for use in the hostile environments
The high level of radiation tolerance inherent in the
ARH design is the result of extensive research, thorough
analysis and testing and of careful component
specification. Designed to supplement the triple output
configuration provided by the ART series, the ARH
circuit topology is the follow-on to the successful ART
design and incorporates many of the design features
characterizing that product line. Capable of uniform
high performance over long term exposures in radiation
intense environments, this series expands the standard
for distributed power systems demanding high
performance and reliability in the harsh environments.

term hermeticity is assured through use of parallel seam
welded lid attachment along with rugged ceramic pin-
to-package seal. Axial orientation of the leads facilitates
preferred bulkhead mounting placing the converter on
the principal heat-dissipating surface.

Circuit Operation and Application Information
The ARH28XXS series of converters have been designed
using a single ended forward switched mode converter
topology. (Refer to Figure I.) Single ended topologies enjoy
certain advantages in radiation hardened designs in that
they eliminate the possibility of simultaneous turn on of
both switching elements during a radiation induced upset.
In addition, single ended topologies are not subject to
transformer saturation problems often associated with
double ended implementations.
Other key circuit design features include output short circuit
and overload protection, input undervoltage lockout and
an external synchronization input port, permitting operation
at an externally set clock rate. Alternately, a synchronization
output is provided to lock frequencies with another
converter when using more than one converter in a system.
Thermal Considerations
The ARH series of converters is capable of providing
relatively high output power from a package of modest
volume. The power density exhibited by these devices is
obtained by combining high circuit efficiency with effective
methods of heat removal from the die junctions. Good
design practices have effectively addressed this
requirement inside the device. However when operating
at maximum loads, heat generated at the die junctions
depends upon minimally restricted thermal conduction from
the base plate for that heat to be carried away. To maintain
case temperature at or below the specified maximum of
125°C, this heat can be transferred by attachment of the
ARH28XXS to an appropriate heat dissipater held in intimate
contact with the converter base-plate.
The design incorporates a two-stage LC input filter to
attenuate input ripple current. A low overhead linear bias
regulator provides both a bias voltage for the converter
primary control logic and a stable, well-regulated reference
for the error amplifier. Output control is realized using a
wide band discrete pulse width modulator control circuit
incorporating a unique non-linear ramp generator circuit.
This circuit helps stabilize loop gain over variations in line
voltage for superior output transient response. Nominal
conversion frequency has been selected as 250 KHz to
maximize efficiency and minimize magnetic element size.
Output voltages are sensed and fed back to the controller
using a patented magnetic feedback circuit. This circuit is
designed to be relatively insensitive to variations in
temperature, aging, radiation and manufacturing tolerances
making it particularly well suited to radiation hardened
designs. The control logic has been designed to use only
radiation tolerant components, and current paths include
series resistances to limit photocurrents.
Effectiveness of this heat transfer is dependent on the
intimacy of the baseplate to heatsink interface. It is therefore
suggested that a heat-transferring medium possessing
good thermal conductivity be inserted between the
baseplate and heatsink. A material utilized at the factory
during testing and burn-in processes is sold under the

trade name of Sil-Pad 400 . This particular product is an
insulator but electrically conductive versions are also
available. Use of these materials assures optimum surface
contact with the heat dissipater by compensating for minor
surface variations. While other available types of heat
conducting materials and thermal compounds provide
similar effectiveness, these alternatives are often less
convenient and are sometimes messy to use.
Inhibiting Converter Output
As an alternative to application and removal of the DC
voltage at the input, the user can control the converter
output by providing an input referenced, TTL compatible,
logic signal to the enable pin 3. This port is internally pulled
“high” so that when not used, an open connection on the
pin permits normal converter operation. When inhibited
outputs are desired, a logical “low” on this port will shut the
converter down. An open collector device capable of
sinking at least 100 µA connected to enable pin 3 will work
well in this application.

operate at the same clock frequency.
Output Short Circuit Protection
While the internal input filter maintains input ripple current
below 50 mAp-p, an external filter can be applied to further
attenuate this ripple to a level below the CE03 limits imposed
by MIL-STD-461. International Rectifier currently supplies
such a filter housed in a complementary package. The
Protection against accidental short circuits on the output
is provided in the ARH28XXS converter. This protection is
implemented by sensing primary switching current and
reducing the switching pulse widths when a short occurs.
The output current is therefore limited to a maximum value,
which protects the converter. Under this condition the
internal power dissipation is nearly the same as for
maximum loading.
catalog number of this part is ARF461.
Output Noise
When attempting noise measurement at the output of
switching converters, measurement techniques employed
can have a significant influence on results during these
tests. Any noise measurements should be undertaken
only with test leads dressed as close to the device output
pins as is physically possible. Probe ground leads should
be kept to a minimum (<< 1") length to minimize the influence
Input Undervoltage Protection
A minimum voltage is required at the input of the converter
to initiate operation. This voltage is set to a nominal value
of 16.8 volts. To preclude the possibility of noise or other
voltage variations at the input falsely initiating and halting
converter operation, a hysteresis of approximately 1.0
volts is incorporated into this circuit. The converter is
guaranteed to operate at 18 Volts input under all specified
conditions.
of parasitic impedances on results.
Input Filter
To attenuate input ripple current, the ARH28XXS series
converters incorporate a two-stage LC input filter illustrated
in Figure III following. The elements of this filter comprise
the dominant input load impedance characteristic, and
therefore determine the nature of the current inrush at
turn-on.

Radiation Performance
A principal design goal was achieving a converter topology
that, because of large design margins, had radiation
performance essentially independent of radiation induced
element-lot performance variations. Where such margins
cannot be assured, element lots are either selected
following RLAT characterization as radiation hard devices
or, purchased as radiation hard devices so that realization
of the design goals are maintained.
The radiation tolerance characteristics inherent in the
ARH28XXS converters are a result of a carefully planned
ground-up design program with specific radiation design
goals. Identification of the general circuit topology, a
fundamental task in the design effort, was followed by
selection of appropriate elements from a list of devices for
which extensive radiation effects data was available. By
imposing sufficiently large margins on those electrical
parameters showing the worst case degrading effects of
radiation, designers were able to select appropriate
elements for incorporation into the circuit. Existing radiation
data was utilized for input to PSPICE and RadSPICE in the
generation of circuit performance verification analyses.
Thus, electrical performance capability under all
environmental conditions including radiation was well
understood before first application of power to the inputs.
