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
The TMR-1 and TMR 1SM series are families of isolated 1 W dc-dc converter mod-
ules 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 fea-
tures 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.
