description the interpoint ? smtr series? of 28 volt dc-dc converters offers up to 30 watts of output power from single or dual configurations. they operate over the full military temperature range of -55c to +125c with up to 84% efficiency. smtr converters are packaged in hermetically sealed metal enclosures, making them ideal for use in military, aerospace and other high reliability applications. s creening smtr converters offer screening options to space prototype (o), class h or k and radiation hardness assurance (rha) levels p - 30 krad(si), l - 50 krad(si) or r - 100 krad(si). single event effects (see) let performance to 86 mev cm 2 /mg. see table 9 on page 13 and table 10 on page 14 for more information. c onverter d esign the smtr converters are constant frequency, pulse-width mod ulated switching regulators which use a quasi-square wave, single ended, forward converter design. tight load regulation is maintained by using a wide bandwidth magnetic feedback and, on single output models, through use of remote sense. on dual output models, the positive output is independently regulated and the negative output is cross regulated through the use of tightly- coupled magnetics. smtr converters have an internal input filter that helps reduce the need for external components in normal operation. use our sfmc emi input filter to meet the requirements of mil-std- 461cs ce03. for the lowest noise performance, connection of the case to input common is recommended. the connection can be hard-wired or ac coupled with a small ceramic bypass capacitor. indefinite short circuit protection and overload protection are provided by a constant current-limit feature. this protective system senses current in the converters secondary stage and limits it to approximately 140% of the maximum rated output current. s ynchronization synchronizing the converter with the system clock allows the designer to confine switching noise to clock transitions, minimizing interference and reducing the need for filtering. in sync mode, the converter will run at any frequency between 500 khz and 675 khz. the sync control operates with an active high at any duty cycle between 40% and 60%. the sync pin should be connected to input common pin when not in use. w ide v oltage r ange smtr converters are designed to provide full power operation over the input voltage range of 16 to 40 volts. operation below 16 volts, including mil-std-704d emergency power conditions is possible with derated power. refer to the low line dropout graph, figure 22 on page 10, for details. features ? radiation tolerant space dc-dc converter - single event effects (see) let performance to 86 mev cm 2 /mg - total ionizing dose (tid) guaranteed per mil-std-883 method 1019, radiation hardness assurance (rha) p = 30 krad(si), l = 50 krad(si), r = 100 krad(si) - 50 - 300 rad(si)/sec dose rate (condition a) - 10 mrad(si)/sec dose rate (condition d) ? operating temperature -55 to +125c ? qualified to mil-prf-38534 class h and k ? input voltage range 16 to 40 volts ? transient protection 50 volts for 50 ms ? fully isolated, magnetic feedbac k ? fixed high frequency switching, 600 khz typical ? trim function or remote sense on single output models ? inhibit and synchronization functions ? indefinite short circuit protection ? typical efficiency up to 83% models o utput v oltage ( v) single dual 3.3 5 5 12 12 15 15 smtr single and dual dc-dc converters page 1 of 14 smtr rev ac - 2015.10.14 28 volt input C 30 watt crane aerospace & electronics power solutions C interpoint products 10301 willows rd. ne, redmond, wa 98052 +1 425-882-3100 ? power@crane-eg.com www.craneae.com/interpoint crane aerospace & electronics power solutions
i mproved d ynamic r esponse the smtr series feed-forward compensation system provides excellent dynamic response and noise rejection. audio rejection is typically 40 db. the min. to max. step line transient response is typically less than 4%. i nhibit f unction smtr converters provide an inhibit terminal that can be used to disable internal switching, resulting in no output voltage and very low quiescent input current. the converter is inhibited when the inhibit pin is pulled below 0.8 v and enabled when its inhibit pin is left floating. an external inhibit interface should be capable of pulling the converters inhibit pin below 0.8 v while sinking the maximum inhibit current and also allowing the inhibit pin to float high to enable the converter. a voltage should not be applied to the inhibit pin. the open circuit voltage present on the inhibit pin is 9 to 11 v. trim and r emote sense ( available on single output models onl y) r l remote sense connection 2 make connections at load. smtr single output converter 4 3 5 10 1 6 2 2 output common positive input input common sense return positive sense positive output external trim connection 1 make connections at converter. r l output common smtr single output converter 4 3 5 10 1 positive input input common 6 sense return positive sense positive output 1 r t 1 f igure 1: t rim c onnection 1, 2, 3, 4 f igure 2: r emote s ense 2, 3, 4 notes for remote sense and trim 1. when trimming output voltage and/or remote sensing, the total output voltage increase must be less than 0.6 volts at the converters pins. do not exceed maximum power. 2. if neither voltage trim nor remote sense will be used, connect pin 3 to pin 4 and pin 5 to pin 6 or the output voltage will increase by 1.2 volts. 3. caution: the converter will be permanently damaged if the positive remote sense (pin 6) is shorted to ground. damage may also result if the output common or positive output is disconnected from the load with the remote sense leads connected to the load. 4. when using remote sense for voltage compensation or when using remote sense for trim, the output will drift over temperature. contact applications engineering for more information at powerapps@ crane-eg.com trim formulas vout = desired output voltage; r t = trim resistor 3.3 v: r t = 1300 * vout C 4304 1.2475 5 v: r t = 1300 * vout C 6512 1.2475 12 v: r t = 1300 * vout C 15631 1.2475 15 v: r t = 1300 * vout C 19498 1.2475 page 2 of 14 smtr single and dual dc-dc converters smtr rev ac - 2015.10.14 crane aerospace & electronics power solutions www.craneae.com/interpoint 28 volt input C 30 watt
