DC/DC Converters TMR 3WIE Series, 3 Watt CB Scheme Features Wide 4:1 input voltage range Compact SIP-8 package Cost optimized design Temperature range -40C to +85C I/O isolation 1500 VDC Remote On/Off control 3-year product warranty The TMR-3WIE series is a family of isolated 3 W dc-dc converter modules with regulated output, featuring wide 4:1 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 -40C to +85C operation temperature. Further features include remote On/Off control and continuous short circuit protection. The compact dimensions and cost optimized design make this converters an ideal solution for applications in communication equipment, instrumentation and industrial electronics.
