SMT05E_12V Series


18 W (5 A) Non-Isolated DC-DC Converters

The SMT05E_12V series non-isolated DC-DC converter accepts a 10 to 14 VDC input and produces an output that can be trimmed over a very wide 0.8 to 3.63 VDC range to satisfy a broad diversity of semiconductor power needs. Rated at 16.5 W, the converter has a typical efficiency of 91% and can deliver up to 5 A. Standard features include remote On/Off and comprehensive protection against short-circuit and overtemperature conditions. Packaged as a low profile surface-mount module, it has a footprint of 0.45 x 0.8 inch (11.4 x 20.3 mm) and an installed height of only 0.23 inch (5.9 mm).
