TDU 1-1211

DC/DC Converter TDU 1 Series, 1 Watt • Compact 1 Watt converter in DIP-8 package • • • Continuous short circuit protection • • I/O isolation 1’500 VDC • • Efficiency up to 83% Unregulated outputs Operating temperature range -40 to +85 °C without derating Input voltage ranges (±10%): 5, 12, 24 VDC 3-year product warranty The TDU 1 series consists of a set of isolated 1 Watt DC/DC converters with unregulated outputs in a compact DIP-8 package. They are designed to offer a compact low-cost alternative to regulated series with no concession on quality and lifetime. They feature a continuous short circuit protection circuit, I/O-isolation of 1500 VDC and an operating temperature range from –40°C to 85°C without derating. The compact dimensions of these converters make them an ideal solution for many space critical applications in communication equipment, instrumentation and industrial electronics.
