SIL10E Series

Not for New Designs

49.9 W (10 A) Non-Isolated DC-DC Converters

The SIL10E series of non-isolated DC-DC converters comprises eight fixed output models covering voltages from 0.8 to 3.3 VDC and one wide output trim model that can be adjusted over the range 0.8 to 3.63 VDC. All nine models can deliver up to 10 A output current. The 3.3 V fixed output and trimmable models accept a 4.5 to 5.5 VDC input, while all other fixed output models accept a 3 to 5.5 VDC input.

Depending on the particular model, SIL10E series converters offer output power ratings of up to 36.3 W and conversion efficiencies as high as 95%. Standard features include remote On/Off, remote sense and comprehensive protection against short-circuit and over temperature conditions. There is a choice of through-hole vertical or horizontal mounting configurations, to suit board layout and space constraints. The horizontal versions have a 0.5 x 2 inch (12.7 x 50.5 mm) footprint and an installed height of only 0.17 inch (4.3 mm), while the vertical versions have a 0.3 x 2 inch (7.8 x 50.8 mm) footprint and an installed height of 0.5 inch (12.7 mm).
