ghp-series (70v input, single/dual output) 5 2017-05-18 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 l oad current is being provided by one of the out puts. 4. load current split equally betwe en 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% t o 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 exce ss 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 dissipati on with the load set such that v out = 90% of nominal. 9. load step transition time ?? 10 ? s. 10. recovery time is measured from the initiation of the transient to where v out 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 p in (pin 3) to the point where v out = 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 converte r?s output (s). the small preload will reduce the converter?s ?no load? input current fr om approximately 70ma to approximately 30m a. radiation performance characteristics test conditions min typ unit total ionizing dose (gamma) mil-std-883, method 1019 operating bias applied during exposure 100 150 krads (si) single event effects seu, sel, segr, seb heavy ions (let) operating bias applied during exposure, full rated load. vin = 60v, 70v, 100v test lab: texas a & m university 82 mev ? cm 2 /mg

ghp-series (70v input, single/dual output) 7 2017-05-18 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 t he 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 t hat may interfere with the attachment of the converter. 2. place the gasket on the surface reserved for t he 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 tight en by hand (~ 4 inoz) in the sequence shown below. 5. tighten the screws with an appropriate torque driver. torque the screws up to 6 inlb in the sequence shown above. ?
