DC/DC Converters TMR 3 Series, 3 Watt UL 60950-1 Features ◆ Wide 2:1 input voltage range ◆ Fully regulated output voltage ◆ Compact SIP-8 package ◆ Models with 1’500 VDC and 3’000 VDC I/O isolation (functional insulation) ◆ Small footprint ◆ Temperature range –40° to +85°C ◆ High efficiency up to 85% ◆ Short-circuit protection ◆ Remote On/Off control ◆ 3-year product warranty The TMR-3 series is a new family of isolated 3W dc-dc converter modules with regulated output, featuring wide 2:1 input voltage ranges. The product comes in a compact SIP-8 plastic package with a small footprint occupying only 2.0 cm2 (0.3 square in.) of board space. An excellent efficiency allows –40° to +85°C operation temperatures. Further features include remote On/Off control and continuous short circuit protection. The compact dimensions of these converters make them an ideal solution for many space critical applications in communication equipment, instrumentation and industrial electronics.
