70V Input, Single/Dual Output
HYBRID-HIGH RELIABILITY
RADIATION HARDENED
DC-DC CONVERTER
Description
The GHP-Series of DC-DC converters are radiation
hardened, high reliability converters specifically designed in
response to the need for moderate power, high efficiency
and well regulated output required by the modern day space
design applications. Their small size and low weight make
them ideal for applications such as geostationary earth orbit
satellites and deep space probes. They exhibit a high tolerance to total ionizing dose, single event effects and environmental stresses such as temperature extremes, mechanical
shock, and vibration.
The converters incorporate a fixed frequency single ended
forward topology with magnetic feedback and an internal
EMI filter that utilizes multilayer ceramic capacitors that are
subjected to extensive lot screening for optimum reliability.
By using two stage filtering these converters produce low
input and output noise. External inhibit and synchronization
input and output allow these converters to be easily incorporated into larger power systems. They are enclosed in a
hermetic 3" x 2" x 0.475" package constructed of an Aluminum-Silicon-Carbide (AlSiC) base and an Alloy 48 ring
frame and they weigh less than 110 grams. The package
utilizes rugged ceramic feed-through copper core pins and
is sealed using parallel seam welding.
Manufactured in a facility fully qualified to MIL-PRF-38534,
these converters are fabricated utilizing DLA Land and
Maritime qualified processes. For available screening
options, refer to device screening table in the data sheet.
Non-flight versions of the GHP-Series converters are
available for system development purposes. Variations in
electrical specifications and screening to meet custom
requirements can be accommodated.

Notes: Electrical Performance Characteristics Table
1. Parameter is tested as part of design characterization or after design changes. Thereafter, parameter shall be guaranteed to the
limits specified.
2. Parameter verified during line and load regulation tests.
3. Output load current must be distributed such that at least 20% of the total load current is being provided by one of the outputs.
4. Load current split equally between outputs on dual output models.
5. Cross regulation is measured with 20% rated load on output under test while changing the load on the other output from 20% to 80% of rated.
6. Guaranteed for a DC to 20 MHz bandwidth. Tested using a 20 kHz to 10 MHz bandwidth.
7. Capacitive load may be any value from 0 to the maximum limit without compromising dc performance. A capacitive load in excess
of the maximum limit may interfere with the proper operation of the converter’s overload protection, causing erratic behavior during turn-on.
8. Overload power dissipation is defined as the device power dissipation with the load set such that VOUT = 90% of nominal.
9. Load step transition time 10 s.
10. Recovery time is measured from the initiation of the transient to where VOUT has returned to within ±1% of its steady state value.
11. Line step transition time 100 s.
12. Turn-on delay time from either a step application of input power or a logic low to a logic high transition on the inhibit pin (pin 3) to the point
Where VOUT = 90% of nominal.
13. Total regulation at EOL is +/- 3% maximum.
14. The input current is minimized with an output load of 300mW to 400mW. If a system design requires converter operation at or near zero
load (e.g. a system standby mode), then it is recommended that a resistive preload of 300mW to 400mW will be added to converter’s
output (s). The small preload will reduce the converter’s “no load” input current from approximately 70mA to approximately 30mA.

Application Notes:
A) Attachment of the Converter
The following procedure is recommended for mounting the converter for optimum cooling and to circumvent any potential
damage to the converter.
Ensure that flatness of the plate where GHP converter to be mounted is no greater than 0.003” per linear inch. It is
recommended that a thermally conductive gasket is used to promote the thermal transfer and to fill any voids
existing between the two surfaces. HiRel recommends Sil-Pad 2000 with the thickness of 0.010".The shape of the gasket should
match the footprint of the converter including the mounting flanges. The gasket is available from IR HiRel. The GHP-Series
converter requires either M3 or 4-40 size screws for attachment purposes.
The procedure for mounting the converter is as follows:
1. Check all mounting surfaces and remove foreign material, burrs, if any or anything that may interfere with the
attachment of the converter.
2. Place the gasket on the surface reserved for the converter and line it up with the mounting holes.
3. Place the converter on the gasket and line both up with mounting holes.
4. Install screws using appropriate washers and tighten by hand (~ 4 in·oz) in the sequence shown below.
5. Tighten the screws with an appropriate torque driver. Torque the screws up to 6 in·lb in the sequence shown above.

B) Output Voltage Adjustment.
Single Output:
To adjust the output voltage of the single output models, a resistor (RADJ) is connected between the Adjust pin (Pin 12)
and either the positive or negative remote sense pins, depending on whether the output voltage is to be adjusted higher
or lower than the nominal set-point. This allows the outputs to be reliably adjusted by approximately +10% to -20% of
the nominal output voltage. Refer to Fig. 3 and use equations provided to calculate the required resistance (RADJ).
Note: The output voltage adjust equation does not work as described for the 3.3V Single model. The adjust
range for 3.3V model is limited to 3.252V to 3.460V.
Fig 3. Configuration for Adjusting Single Output Voltage
For all Single Output Models, to adjust the output voltages higher:
Where: RADJ is in kOhms
RADJ is connected to the -Out pin and VNOM < VOUT < 1.1VNOM (Fig. 3, Note 2)
VNOM is the nominal output voltage with the Adjust pin left open
VOUT is the desired output voltage
For all Single Output Models, to adjust the output voltages lower:
Where: RADJ is in kOhms
RADJ is connected to the +Out pin and 0.8VNOM < VOUT < VNOM (Fig. 3, Note 1)
VNOM is the nominal output voltage with the Adjust pin left open
VOUT is the desired output voltage
8
2017-05-18
GHP-SERIES
(70V Input, Single/Dual Output)
Dual Output:
To adjust the output voltage of the dual output models, a resistor (RADJ) is connected between the Adjust pin (Pin 8) and
either output. This allows the outputs to be reliably adjusted by approximately +10% to -20% of the nominal output voltage.
Refer to Figure 9 and use equations provided to calculate the required resistance (RADJ).
Fig 4. Configuration for Adjusting Dual Output Voltage
For all Dual Output Models, to adjust the output voltages higher:
Where: RADJ is in kOhms
RADJ is connected to the -Out pin and VNOM < VOUT < 1.1VNOM (Fig. 4, Note 2)
VNOM is the nominal output voltage with the Adjust pin left open
VOUT is the desired output voltage
For all Dual Output Models, to adjust the output voltages lower:
RADJ =
8 x (VNOM – 1.25) x ( VOUT – 1.25)
- 75
VNOM - VOUT
Where: RADJ is in kOhms
RADJ is connected to the +Out pin and 0.8VNOM < VOUT < VNOM (Fig. 4, Note 1)
VNOM is the nominal output voltage with the Adjust pin left open
VOUT is the desired output voltage

 CK is a DLA Land and Maritime (formerly DSCC) part marking used to designate a Class K compliant hybrid.
The CK marking does not indicate the hybrid is radiation certified.
No Suffix is a radiation rated device but not available as a DLA Land and Maritime qualified SMD per MIL-PRF-38534.
 Any Engineering Model (EM) build with the “EM” Suffix shall only be form, fit and functional equivalent to its
Flight Model (FM) counterpart, and it may not meet the radiation performance. The EM Model shall not be expected
comply with MIL-PRF-38534 flight quality/workmanship standards, and configuration control. An EM build may use
electrical equivalent commercial grade components. IR HiRel will provide a list of non-compliance items upon request.
