SMT05E Series 19.9 Watt (5 Amp) Non-Isolated DC-DC Converters


The SMT05E series of non-isolated DC-DC converters comprises two models, both of which accept a 3 to 5.5 Vdc input. One model produces a fixed 1.5 Vdc output, the other produces an output that can be trimmed over a very wide 0.75 to 3.63 Vdc range to satisfy a broad diversity of semiconductor power needs. Both converters can deliver up to 5 amps output current; the 1.5 V output model is rated at 8.25 watts and has a typical efficiency of 87.5%, while the trimmable output model is rated at 18.15 watts and has a typical efficiency of 94%.

Both SMT05E series converters feature remote On/Off and comprehensive protection against short-circuit and overtemperature conditions. Packaged as low profile surface-mount modules, they have a 0.45 x 0.8 inch (11.4 x 20.3 mm) footprint and an installed height of only 0.26 inch (6.7 mm).
