1 / 3 page  GS15T48-5 15W DC-DC CONVERTER December 1993 1/3 Type Vin Vout Iout GS15T48-5 40 to 60 V 5 V 3 A DESCRIPTION The GS15T48-5 is a 15W DC-DC converter de- signed to provide a 5V/3A isolated output from a 48V input in a metal package. High frequency forward switching configuration en- sures high efficiency (80% typ.); input filter mini- mizes 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.
