| GS15T48-5 15W DC-DC CONVERTER Type GS15T48-5 Vin 40 to 60 V Vout 5V Iout 3A DESCRIPTION The GS15T48-5 is a 15W DC-DC converter designed to provide a 5V/3A isolated output from a 48V input in a metal package. High frequency forward switching configuration ensures high efficiency (80% typ.); input filter minimizes reflected input current and continuous short-circuit protection is provided. The integral heatsinkallows a large power handling capability and it features also an effective shielding to minimize EMI.
