TRACOPOWER TRS 2 DC/DC Converter, 5V dc/ 400 mA, 18V dc Input, 9V Input 2 W, Surface, 90 °C Max Temp -40 °C Min Temp,

TRS 2 Series is a new series with the design purpose to improve the prevalent 2 Watt SMD DC/DC converters in terms of size, cost, efficiency and performance. The main intended uses for the TRS 2 Series are IT applications, industrial control systems and also measurement equipment. With the reduction of thermal loss, the operating temperature range can be expanded from -40°C to +90°C. The converters are fully regulated over 0 - 100% load (no minimum load is required). The low input range is extended from 4.5 to 13.2 VDC (to include 12V battery powered applications) while models are also available with the standard 2:1 input ranges of 9-18, 18-36 and 36-75 VDC.

Most compact 2 Watt SMD DC/DC converter: 11.9 mm x 11.3 mm x 8 mm (0.47 x 0.44 x 0.31 inch)
