DESCRIPTION
The GS15T48-5 is a 15W DC-DC converter designed to provide a 5V/3A isolated output from a
48Vinputin a metalpackage.
High frequencyforwardswitchingconfigurationensures high efficiency (80% typ.); input filter minimizes reflected input current and continuous
short-circuit protectionis provided.
Theintegralheatsinkallows alargepowerhandling
capabilityand it features alsoan effectiveshielding
to minimizeEMI.
