Safe Operating Range

The parameters of the safe operating range are tested in typical experiment environments. It is recommended to measure the surface temperature of the buck converter to determine if the dissipation needs to be improved.

Surface temperature < 80℃: the converter performs steadily
Surface temperature in 80 - 90℃: dissipation improvement recommended
Surface temperature >90℃: dissipation improvement is required since the overheat protection may be triggered at any time.
