pads for increased current handling and better heat transfer. These are
indicated with the “R” designator in the model number, LSM2-T/30-D12 -C.
MPS recommends that users lay out their PC boards to accept these two
pads for larger current applications. Please note that the Derating curves for
the “R” models accept higher temperature and greater current limits than
units without the additional pads.
The LSM2-T/30-D12 is optionally available with two additional ground

must have a substantial area of several square inches of copper etch fl ow-
soldered to these pads and suffi cient feed-throughs or other means of con-
ducting current. The “R” pads and the standard pads 1 and 2 are in parallel.
nect to these ground pads, order model LSM2-T/30-D12-C without the “R”
designator. Please observe the lower Derating curves for standard, “non-R”
models.
