DC/DC Converters TMR 2 Series, 2 Watt Features ◆ Wide 2:1 input voltage range ◆ Compact SIP-8 package ◆ Small footprint ◆ Full SMD design ◆ Temperature range –40° to +85°C ◆ High efficiency ◆ Excellent load and line regulation ◆ Indefinite short-circuit protection ◆ I/O isolation 1000VDC ◆ Remote On/Off control ◆ Fully RoHS compliant ◆ 3-year product warranty UL 60950-1 The TMR-2 series is a family of isolated 2W 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 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 ultra-compact dimensions of these converters make them an ideal solution for many space critical applications in communication equipment, instrumentation and industrial electronics.
