Application Guide
The power dissipation of the LM2596/LM2596HV Buck Converter Module is internally limited. Small sized PCB and thermal resistance of IC package have limited the power dissipation of the module.
Depending on the conversion condition, 3A full loading is not might possible due to the internally limited power dissipation.
