TRACO Power North America, Inc. DC DC Converters TSN 1-2480

The Traco Power DC-DC Converter, part number 45Y3508, is a non-isolated step-down switching regulator designed for negative output applications. It operates within a wide input voltage range of -10.5V to -32V and provides a fixed output of -8V at a maximum current of 1A, delivering up to 8W of output power. The converter boasts high efficiency, reaching up to 96%, which allows for operation at full load up to +70°C without the need for a heatsink. This model features excellent line and load regulation, with a voltage set accuracy of ±2% at full load. It includes protections against overload, short circuit, and over-temperature, ensuring reliable performance in various conditions. The operating temperature range is from -40°C to +85°C, making it suitable for demanding environments. The converter is also designed to have low standby current and does not require external capacitors, simplifying integration into existing designs. With a compact size and pin compatibility with LM79xx linear regulators, this converter is a viable option for engineers looking to replace less efficient linear solutions in their projects.
