DC/DC Converters TDR 2 Series, 2 Watt Features ◆ Compact design in SMD or DIP package ◆ Wide 2:1 input voltage range ◆ Fully regulated outputs ◆ Low ripple and noise ◆ No minimum load required ◆ Temperature range –40°C to +85°C without derating ◆ I/O isolation 1500 VDC ◆ Continuous short-circuit protection ◆ Remote On/Off control ◆ Fully RoHS compliant ◆ 3-year product warranty The TDR-2 series is a family of compact 2 W dc/dc-converters with 2:1 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 without power derating, continuous short circuit protection and excellent immunity against environmental influences make these converters very reliable. A TDR-2 converter is the ideal solution for space critical high end applications in communication equipment, instrumentation and industrial electronics.
