  • 18 Pin DIP Package
  • 3.5 Million Hour MTBF
  • Meets FCC/EN55022 Class A
  • UL and CSA approved
  • No External Components Required
  • Adjustable Output Voltage Power T rends’ PT4200 series of isolated DC to DC converters advance the state-of-the- art for board-mounted converters by employing high switching frequencies, thick-film technology and a high degree of silicon integration. The high reliability and very low package height makes these converters ideal for Telecom and Datacom applications requiring input-to-output isolation with board spacing down to 0.6”. The PT4200 series is offered in a unique molded through-hole or SMD-DIP package with single output voltages of 2V , 3.3V , 5V , and 12V , dual outputs of ±5V , +5V/+3.3V, and ±12V .
