DC/DC Converters TRA 3 Series, 3 Watt CB Scheme Features ◆ Semi-regulated output (load) ◆ Highest power density 3W SIP-Converter ◆ Industry standard pinout ◆ High efficiency up to 89% ◆ I/O isolation voltage 1000 VDC ◆ Operating temperature range UL 60950-1 –40°C to +85°C ◆ 3-year product warranty The TRA 3 series are miniature, I/O-isolated 3W DC/DC-converters with a semi load regulation. They are the ideal solution to power drivers and circuits where unregulated DC/DC converters do not meet the input voltage range at load change.
