PT42/4300 Series 3-7 Watt 48V-Input Isolated DC/DC Converter SLTS023B (Revised 1/3/2002) • • • • • • • • • 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 The PT4200 series of isolated DC/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.
