DC/DC Converters TMR 2E Series, 2 Watt Features ◆ Wide 2:1 input voltage range ◆ Compact SIP-8 package ◆ Cost optimized design ◆ Temperature range –40° to +85°C ◆ I/O isolation 1000VDC ◆ Remote On/Off control ◆ Fully RoHS compliant ◆ 3-year product warranty The TMR-2E 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 temperature. Further features include remote On/Off control and continuous short circuit protection. The compact dimensions and cost optimise design make this converters an ideal solution for applications in communication equipment, instrumentation and industrial electronics.
