About thermal derating curve of output current *It is a setup of commonness of MPM01/04.
Thermal derating curve of the figure 6 is without the radiator which is a standard use condition fundamentally of MPM01/04.
By the use of cooling-fan / radiator installation, output current beyond 3A can't be agreed.
OCP(overcurrent protection) threshold value can't be changed, because it is fixed by built-in MIC.
*With package design of MPM00, though radiator installation is possible by the screw, keep the following strictly:
1) You must surely use load current with less than 3Amps.
2) You must use the radiator of the form that package surface temperature is less than 100℃.
(But, ambient temperature "Ta" makes 85℃ an upper limit.)
