(figure 1) it should also be noted that the inductance and the frequency of the lc filtering network should be staggered with the dc/dc frequency to avoid mutual interference. 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 sees (table 1). external capacitor table (table 1) vin cin single vout cout dual vou t cout (vdc) ( f) (vdc) ( f) (vdc) ( f) 5 4.7 5 10 5 4.7 12 2.2 9 4.7 9 2.2 24 1 12 2.2 12 1 -- -- 15 1 15 1 it's not recommend to connect any external capacitor in the application field with less than 0.5 watt output. output voltage regulation and over-voltage protection circuit the simplest device for output voltage regulation, over-voltage and over-current protection is a linear voltage regulator with overheat protection that is connec ted to the inp ut or out put end in ser i es (f ig ur e 2) . overload protection under normal operating conditions, the output circuit of these products has no protection against overload. the simplest method is to connect a self-recovery fuse in series at the input end or add a circuit breaker to the circuit. no parallel connection or plug and play. note: 1. all specifications measured at ta=25 , humidity<75%,nominal input voltage and rated output load unless otherwise specified. 2. only typical models listed, other models may be different, please contact our technical person for more details. 3. operation under minimum load will not damage the converter; however, they may not meet all specification listed. microdc professional power module,inc. tel:0086-20-86000646 e-mail:tech@microdc.cn website:http://www.microdc.cn rohs compliant information this series is compatible with rohs soldering systems with a peak wave solder temperature of 300 c for 10 seconds. the pin termination finish on the sip package type is tin plate, hot dipped over matte tin with nickel preplate. the dip types are matte tin over nickel preplate. both types in this series are backward compatible with sn/pb soldering systems. reach compliant information this series has proven that this product does not contain harmful chemicals, it also has harmful chemical substances through the registration, inspection and approval.
