(see figure 1) if you want to further decrease the input/output ripple, you can increase capacitance properly or choose capacitors with low esr. if the capacitance is too big, a startup problem might arise. the maximum allowable capacitance to ensure safe and reliable operation is listed in table 1. general: cin: 10 ~ 47 f cout: 10 f / 100 ma 3. remote on/off when open or high impedance,the converter will be on; when this pin is ?high?; the converter will shutdown; it should be noted that the input current (ic) should between 5 ~ 10 ma, exceeding the maximum 20 ma will cause permanent damage to the converter. the value of r can be derived as follows : 4. input current when using an unstable power source, please ensure the output voltage and ripple voltage do not excced indexes of the converter. the preceding power source must be able to provide for converter suf cient starting current ip. general: ip 1.6*iin-max 5. no parallel connection or plug and play single output +v o 0v cout 3 5 cin vin gnd 2 1 6 vc r ic d1 dc/dc dual output +v o 0v cout 3 5 4 cout -vo cin vin gnd 2 1 6 vc r ic d1 dc /dc single vout (vdc) cout (f) dual vout (vdc) cout (f) 3.3 2,200 -- -- 5 1,000 5 680 12 470 12 330 15 330 15 220 table 1 r = v c - v d - 1.0 i c figure 1 application notes discontinued
