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.
