(see figure 3). if you want to further decrease the input/output ripple, you can increase capacitance properly or choose capacitors with low esr. however, the capacitance of the output filter capacitor must be proper. if the capacitance is too big, a startup problem might arise. for every channel of output, provided the safe and reliable operation is ensured, the greatest capacitance of its filter capacitor must less than the max. capacitive load. general: cin: 10 f~47 f cout:10 f/100ma single output dual output +vo 0v cout 3 5 cin vin gnd 2 1 6 vc r ic d1 dc/dc +vo 0v cout cin vin gnd 2 1 6 vc r cout -vo 3 4 5 ic d1 dcdc / (figure 3) 4) ctrl terminal when open or high impedance, the converter work well; when this pin is high level ; the converter shutdown; it should be note that the input current should between 5-10ma,exceeding the maximum 20ma will cause permanence damage to the converter. the value of r can be derived as follows: c d c i v v r 0 . 1 - - = 5) input current nominal input voltage range. the input current of the power supply must be sufficient to the startup current (ip) of the dc/dc module (figure 4). general: ip 1.6*iin-max i n p u t c u r r e n t ( a ) input voltage (v) input voltage range ip (figure 4) 6) no parallel connection or plug and play note: 1. the load shouldn't be less than 10%, otherwise ripple will increase dramatically. operation under minimum load will not damage the converter; however, they may not meet all specification listed. 2. max. capacitive load tested at input voltage range and full load. 3. all specifications measured at ta=25 c, humidity<75%, nominal input voltage and rated output load unless otherwise specified. 4. in this datasheet, all the test methods of indications are based on corporate standards. 5. only typical models listed, other models may be different, please contact our technical person for more details. 6. our company offer custom products. 7. specifications subject to change without notice. mornsun science & technology co.,ltd. address: no. 5, kehui st. 1, kehui development center, science ave., guangzhou science city, luogang district, guangzhou,p.r.china. tel: 86-20-28203030 fax:86-20-38601272 http://www.mornsun-power.com
