http://www.tracopower.com Page 1 of 4

DC/DC Converters

TDR 3WI Series, 3 Watt

Features

◆ Compact design in SMD or DIP package

◆ Ultra wide 4:1 input voltage range

◆ Fully regulated outputs

◆ Low ripple and noise

◆ No minimum load required

◆ Temperature range –40°C to +85°C

◆ I/O isolation 1500 VDC

◆ Continuous short-circuit protection

◆ Remote On/Off control

◆ Fully RoHS compliant

◆ 3-year product warranty The TDR-3WI series is a family of compact 3 W dc/dc-converters with 4:1 input

voltage ranges and tightly regulated output voltages even under no load conditions.

The product is available in SMD-package or in DIP-package. They work with high

efﬁciency over the full load range and come with a remote On/Off input.

The usability in temperature ranges of up to +85°C, continuous short circuit protec-

tion and excellent immunity against environmental inﬂuences make these converters

very reliable.

A TDR-3WI converter is the ideal solution for space critical high end applications in

communication equipment, instrumentation and industrial electronics.
