model selection guide mechanical dimensions notes: 1. load regulation is measured for an output change of 20% to 100%. 2. when measuring output ripple, it is recommended that an external 0.33 f ceramic capacitor be placed from each output to the common pin. for noise sensitive applications, the use of 3.3 f capacitors will reduce the output ripple. 3. operation at no-load will not damage these units. however, they may not meet all speci cations. 4. the converter should be connected to a low ac-impedance source. an input source with a highly inductive impedance may affect the stability of the con- verter. 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 (esr <1.0 ? at 100 khz) capacitor be mounted close to the converter. for 5v input units a 2.2 f is recommended; a 1.0 f for 12v input units; and for 24v input models, a 0.47 f. 5. units may be connected to provide a 10 vdc, 24 vdc or 30 vdc output. to do this, connect the load across the positive (+vout) and negative (-vout) outputs and oat the output common. 6. 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. 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 load regulation (%, max) 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 ml105d-05 5 4.5 - 5.5 270 30 5.0 100 2.0 10 74 33 500 ml105d-12 5 4.5 - 5.5 259 30 12.0 42 0.8 8 78 33 500 ml105d-15 5 4.5 - 5.5 254 30 15.0 33 0.7 7 78 33 500 ml112d-05 12 10.8 - 13.2 113 15 5.0 100 2.0 8 74 33 200 ml112d-12 12 10.8 - 13.2 108 15 12.0 42 0.8 5 78 33 200 ml112d-15 12 10.8 - 13.2 104 15 15.0 33 0.7 5 79 33 200 ml124d-05 24 21.6 - 26.4 57 9 5.0 100 2.0 8 73 33 100 ml124d-12 24 21.6 - 26.4 54 9 12.0 42 0.8 5 78 33 100 ml124d-15 24 21.6 - 26.4 53 9 15.0 33 0.7 5 78 33 100 pin description 1- v i n 2+vin 3 no pin 4 common 5 -vout 6 no pin 7 +vout 8 no pin 9 no pin 10 na na = not for electrical connection pin connections board layout derating curve 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
