DC/DC Converters TMR 1 & TMR 1SM Series, 1 Watt Features ◆ Wide 2:1 input voltage range ◆ Compact SIP-6 or SMD package ◆ Fully regulated outputs ◆ Cost optimised design ◆ No minimum load required ◆ Continuous short circuit protection ◆ Temperature range –40°C to +85°C ◆ I/O isolation 1500 VDC ◆ Remote On/Off control (SMD) ◆ 3-year product warranty CB Scheme The TMR-1 and TMR 1SM series are families of isolated 1 W dc-dc converter modules with regulated output, featuring wide 2:1 input voltage ranges. These products come in a compact SIP-6 or SMD package with small footprint occupying only 1.2 cm2 (0.2 square inch) of board space. An excellent efficiency allows –40°C to +85°C operation temperature. Further features include remote On/Off control (SMD-Version) and continuous short circuit protection. The compact dimensions and cost optimised design make this converters an ideal solution for applications in communication equipment, instrumentation and industrial electronics.
