DC/DC Converter TRS 2 Series, 2 Watt
Models
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 measure-
ment 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 stan-
dard 2:1 input ranges of 9-18, 18-36 and 36-75 VDC. The functional I/O-isolation system
is designed to meet IEC/EN 62368-1 with a test voltage (60 s) of 1600 VDC.
