model selection guide mechanical dimensions notes: 1. the speci ed maximum capacitive load is for each output. 2. when measuring output ripple, it is recommended that an external 0.47 f ceramic capacitor be placed from +v out to -v out for single output models or from each output to common for dual output models. for noise sensitive applications, the use of 3.3 f capacitors will reduce the output ripple. 3. transient recovery is measured to within a 1% error band for a load step change of 75% to 100%. 4. the control input is current controlled. the unit operates when this input is open. when the input is ?igh (current is owing into the pin), the converter shuts down. the input current to this pin should be applied via a 1 k resistor, and kept between 2 ma to 4 ma. connecting this input directly to ground will not damage the converter. 5. the recommended re ow settings are a peak tem- perature of 245 ? for a maximum period (t pk ) of 10s notes: all dimensions are typical in inches (mm) tolerance x.xx = ?.01 (?.25) pin 1 is marked by a ?ot or indentation on the unit model number input output ef ciency (%, typ) output capacitive load ( f, max) fuse rating slow-blow (ma) voltage (vdc) current (ma) voltage (vdc) current (ma, max) current (ma, min) nominal range full-load no-load ml105s-05rw 5.0 4.5 - 9.0 256 40 5.0 200 0.0 78 1,680 500 ml105s-12rw 5.0 4.5 - 9.0 252 40 12.0 83 0.0 79 820 500 ml105s-15rw 5.0 4.5 - 9.0 248 40 15.0 67 0.0 81 680 500 ml105d-12rw 5.0 4.5 - 9.0 255 40 12.0 42 0.0 79 470 500 ML105D-15RW 5.0 4.5 - 9.0 248 40 15.0 33 0.0 80 330 500 ml112s-05rw 12 9.0 - 18.0 105 20 5.0 200 0.0 79 1,680 200 ml112s-12rw 12 9.0 - 18.0 105 20 12.0 83 0.0 79 820 200 ml112s-15rw 12 9.0 - 18.0 102 20 15.0 67 0.0 82 680 200 ml112d-12rw 12 9.0 - 18.0 104 20 12.0 42 0.0 81 470 200 ml112d-15rw 12 9.0 - 18.0 103 20 15.0 33 0.0 80 330 200 ml124s-05rw 24 18.0 - 36.0 53 10 5.0 200 0.0 79 1,680 100 ml124s-12rw 24 18.0 - 36.0 51 10 12.0 83 0.0 82 820 100 ml124s-15rw 24 18.0 - 36.0 51 10 15.0 67 0.0 82 680 100 ml124d-12rw 24 18.0 - 36.0 51 10 12.0 42 0.0 82 470 100 ml124d-15rw 24 18.0 - 36.0 50 10 15.0 33 0.0 82 330 100 ml148s-05rw 48 36.0 - 75.0 26 7 5.0 200 0.0 79 1,680 50 ml148s-12rw 48 36.0 - 75.0 26 7 12.0 83 0.0 80 820 50 ml148s-15rw 48 36.0 - 75.0 26 7 15.0 67 0.0 80 680 50 ml148d-12rw 48 36.0 - 75.0 26 7 12.0 42 0.0 81 470 50 ml148d-15rw 48 36.0 - 75.0 25 7 15.0 33 0.0 81 330 50 pin single dual 1-v in -v in 2 remote on/off 7nc nc 8 nc common 9+v out +v out 10 -v out -v out 16 +v in +v in nc = no connection pin connections board layout derating curve , all other outputs micropower direct we power your success - for less! 292 page street ste d stoughton, ma 02072 ? tel: (781) 344-8226 ? fax: (781) 344-8481 ? e-mail: sales@micropowerdirect.com www.micropowerdirect.com and a time above liquidous (t l ) of <60 seconds at 217 ?. for more information, please contact the factory. 6. operation at no-load will not damage these units. however, they may not meet all speci cations. 7. the converter should be connected to a low ac-im- pedance source. an input source with a highly inductive impedance may affect the stability of the converter. in applications where the converter output loading is high and input power is supplied over long lines, it may be necessary to use a capacitor on the input to insure start-up. in this case, it is recommended that a low esr (<1.0? at 100 khz) capacitor be mounted close to the converter. f or 24v input units a 4.7 f is recom- mended and for 48v input models, a 2.2 f. 8. it is recommended that a fuse be used on the input of a power supply for protection. see the table above for the correct rating.
