The SIL15E series are non-isolated dc-dc converters packaged in a single-in-line footprint
giving designers a cost effective solution for conversion from a 12 V source. The SIL15E
offers a range of fixed outputs and one wide trim output unit at an industry leading 15 A
which allows maximum design flexibility and a pathway for future upgrades. The SIL15E is
designed for applications that include distributed power, workstations, optical network and
wireless applications. Implemented using state of the art surface mount technology and
automated manufacturing techniques, the SIL15E offers compact size and efficiencies of up
to 94%.
