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 protection 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.
