Application Notes Mechanical Outline Product Selector Guide Revised 5/15/98
· Wide Input Voltage Range: 38V to 72V · 83% Efficiency · 1,500 VDC Isolation · 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 ends' PT4200 series of isolated r
DC to DC converters advance the state-of-theart 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 T lecom and Datacom e 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. , ,
