DC/DC Converters TMR 2 Series, 2 Watt RoHS Features ◆ Wide 2:1 Input Voltage Range ◆ Compact SIP-8 Package ◆ Small Footprint ◆ Full SMD Design ◆ Temperature Range –40° to +75°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 compliant 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 +75°C operation temperatures at full load. 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.
