PD-97871 GHP-SERIES 120V 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. 1 GHP Features Total Dose > 100 kRads(Si) SEE Hardened to LET up to 82 MeV.cm2/mg Low Weight < 110 grams Low Input & Output Noise Magnetically Coupled Feedback 95V to 140V DC Input Range Up to 120W Output Power Single and Dual Output Models Include 3.3, 5, 6, 12, 15 and ±5, ±12 and ±15V High Efficiency - to 86% -55°C to +125°C Operating Temperature Range 100M @ 500VDC Isolation Under-Voltage Lockout Short Circuit and Overload Protection Adjustable Output with an External Resistor Remote Sense on Single Output Models Synchronization Input and Output External Inhibit > 3.3 Million Hours MTBF Applications Geostationary Earth Orbit Satellites (GEO) Deep Space Satellites / Probes Strategic Weapons and Communication System 2017-05-22 GHP-SERIES (120V Input, Single/Dual Output) Specifications Absolute Maximum Ratings Input Voltage Output power Lead Temperature Operating temperature Storage temperature Recommended Operating Conditions -0.5VDC to +160VDC Internally limited +300°C for 10 seconds -55°C to +125°C -55°C to +125°C Input Voltage Output power Operating temperature Operating temperature1 +95VDC to +140VDC 0 to Max.

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.

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. 7 2017-05-22 GHP-SERIES (120V Input, Single/Dual Output) 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.

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).
