Both the MAX17515 and MAXM17515 are power modules. The MAX17515 has an operational temperature range of -40 to +85C, whereas the MAXM17515 has an operational temperature range of -40C to +125C.
Otherwise, the parts are the same. Note that this is different nomenclature from other Maxim products - usually power modules have "MAXM" in the name and the discrete step-down converter/controller IC in the module has "MAX" in the name.
