| DC/DC Converters TMR 2WI Series, 2 Watt Features Ultra-wide 4: Input Range SIP-9 Package Full SMD Design Temperature Range -40 to +75C High Efficiency Excellent Load and Line Regulation Indefinite Short-circuit Protection I/O-Isolation 500 VDC Remote On/Off Control Fully RoHS compliant 3 Year Product Warranty compliant RoHS 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 -40c to +75C 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.
