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.
