• Please note that when the Vadj is not used, pin 8 must be connected to pin 9.
• Wide Input Voltage Range: 18V to 36V
• 84% 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 The PT4205 series of isolated DC/DC converters employ high switching frequen- cies, 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 isola- tion with board spacing down to 0.6”. The PT4205 series is offered in a unique molded through-hole or SMD-DIP package with single output voltages of 3.3V and 5V. (For dimensions and PC board layout, see Package Style 900.)
