| DC/DC Converters TMR 3 Series, 3 Watt Features Wide 2: Input Voltage Range Ultra-compact SIP-8 Package Small Footprint Full SMD Design Temperature Range -40 to +70C 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-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 ultra-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 +70C operation temperatures at full load. Further features include remote On/Off control and continuous short circuit protection. The very compact dimensions of these converters make them an ideal solution for many space critical applications in communication equipment, instrumentation and industrial electronics.
