SMT15E Series


49.9 W (15 A) Non-Isolated DC-DC Converters

The SMT15E series of non-isolated DC-DC converters comprises two fixed output models offering voltages of 2.5 V or 3.3 V, and one wide output trim model that can adjusted over the range 0.8 to 3.63 VDC. All three models can deliver up to 15 A output current. The 3.3 V fixed output model accepts a 4.5 to 5.5 VDC input, while the other two models accept a 3 to 5.5 VDC input. Depending on the particular model, SMT15E series converters offer output power ratings of to 54.45 W and conversions efficiencies as high as 95%. Standard features include remote On/Off, remote sense and comprehensive protection against short-circuit and overtemperature conditions. Packaged as low profile surface-mount modules, they have a 0.53 x 1.3 inch (13.5 x 33 mm) footprint and an installed height of only 0.32 inch (8.2mm).
