SMT40C2 Series 200 Watt (40 Amp) Non-Isolated DC-DC Converters


The SIL40C2 and SMT40C2 series of 40 amp non-isolated DC-DC converters are designed for cost- and space-sensitive applications. Both converters accept a wide range 4.5 to 13.8 Vdc input and provide an output that is adjustable from 0.6 to 5.0 Vdc to accommodate a wide variety of silicon power needs. Rated at 200 watts, the converters are capable of delivering up to 40 amps and have a typical efficiency of 94%. Standard features include remote sense, remote On/Off and remote ‘power good’ indication. These converters also support current sharing – multiple modules can be connected in parallel.

SIL40C2 series converters offer a choice of through-hole horizontal and through-hole vertical mounting, while the SMT40C2 is a surface-mount module.
