DC/DC Converters TMR 2WI Series, 2 Watt RoHS compliant Features ◆ Ultra-wide 4:1 Input Range ◆ SIP-9 Package ◆ Full SMD Design ◆ Temperature Range –40 to +75°C ◆ High Efficiency ◆ Excellent Load and Line Regulation ◆ Indefinite Short-circuit Protection ◆ I/O-Isolation 1500 VDC ◆ Remote On/Off Control ◆ Fully RoHS compliant ◆ 3 Year Product Warranty The TMR-2WI series is a new family of isolated 2W dc-dc converter modules with regulated output, featuring ultra-wide 4:1 input voltage ranges of 9-36 VDC or 18-75 VDC. The product comes in a ultra-compact SIP-9 plastic package. An excellent efficiency up to 84% allows –40°c to +75°C operation temperatures at full load. Further features include remote On/Off control and continuous short circuit protection. Typical applications for these ultra-compact converters are battery operated equipment and distributed power architectures in communication, instrumentation and industrial electronics, everywhere where space on the PCB is critical.
