Scheme
Features
◆ Wide 4:1 input voltage range
◆ Compact SIP-8 package
◆ Cost optimized design
◆ Temperature range –40°C to +85°C
◆ 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 –40°C to +85°C 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.
