description with a miniature footprint of just 0.79 square inches, the interpoint ? slh series? of 28 volt dc-dc converters delivers 1.5 watts of output power while saving significant board area. the wide input voltage range of 16 to 40 volts accepts the varying voltages of space, military, or aerospace bus power and tightly regulates output voltages to protect downstream components. single output models feature outputs of 5, 12, or 15 volts, and dual output models feature outputs of 5, 12 and 15 volts. s creening slh converters offer screening to class h or k and radiation hardness assurance (rha) levels 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 12 for more information. c onverter d esign slh series dc-dc converters incorporate a flyback topology with a variable switching frequency . feedback provides output voltage regulation. output voltage is magnetically fed back to the input side of the pwm to regulate output voltage. up to 80% of the load of the dual output models may be on one output providing that the other output carries a minimum of 20% of the total load. the dual models can be used as a single output voltage by connecting the load between positive and negative outputs, leaving the common unconnected resulting in double the output voltage. (for example, slh2805d can be used as a 10 volt output.) when used with interpoints stf28-461 filter, the combination will meet the requirements of mil-std-461c, ce03. i nhibit f unction the slh series incorporates an inhibit terminal that can be used to disable internal switching. the converter is inhibited when an active low ( 0.5 v) signal is applied to the inhibit pin (pin 7). in the inhibit mode the inhibit pin sources up to 2 ma maximum. the converter resumes normal operation when an open circuit is applied to the inhibit pin. the open circuit voltage of the inhibit is 7 to 8 volts. do not apply an external pull-up to the converter. p rotection f eature s all models include a soft-start function to prevent large current draw and minimize overshoot. the converters provide short circuit protection (by restricting the current) and output overload protection. c onvenient p ackaging the slh series converters are packaged in hermetically sealed metal cases which provide emi/rfi shielding. 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) l = 50 krad(si), r = 100 krad(si) ? operating temperature -55c to +125c ? qualified to mil-prf-38534 class h and k ? input voltage range 16 to 40 v ? t ransient protection 50 v for 50 ms ? fully isolated magnetic feedback ? fixed high frequency switching ? inhibit function ? indefinite short circuit protection models o utput v olta g e (v) s i ng les d uals 5 5 12 12 15 15 page 1 of 12 slh rev ab - 2015.10.22 crane aerospace & electronics power solutions slh single and dual dc-dc converters 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 28 volt input C 1.5 watt
