The series offers smaller package size, improved efficiency, lower output ripple and 3kVDC isolation capability through the use of state of the art packaging and technology. Ideally suited for providing dual rail supplies on primarily digital boards with the added benefit of galvanic isolation to reduce switching noise. All of the rated power may be drawn from a single pin provided the total load does not exceed 1watt. www.cdpoweronline.com kHrs 195 1121 1035 375 206 205 1697 1557 682 343 188 559 375 243 154 MIN Parameter No Electrolytic or Tantalum Capacitors (pF) 20 22 30 31 32 20 21 26 25 28 29 33 48 55 60 Continuous operation, 3.3V input types 2.97 Voltage Range Continuous operation, 5V input types 4.5 Continuous operation, 12V input types 10.8 3.3V input types Reflected Ripple Current All other types Internal SMD Construction MTTF up to 1.6 Million hours (%) 74 79 75 78 79 77 70 80 76 78 79 74 79 81 82 INPUT CHARACTERISTICS OUTPUT CHARACTERISTICS No External Components Required (mA) 407 383 402 390 384 259 285 249 263 255 253 112 106 104 102 Isolation Capacitance MTTF1 For DIP package style replace suffix S with D, eg NKA0312D. When operated with additional external load capacitance the rise time of the input voltage will determine the maximum external capacitance value for guaranteed start up. The slower the rise time of the input voltage the greater the maximum value of the additional external capacitance for reliable start up.
