6. Thermal Derating
Set this products in a place where good convection is ensured. And also be sure to mount on a board, when using.
This product has been designed to radiate by utilizing the mounted board. So make the line to connect to the converter as
wide as possible. The radiation from GND is especially big, so make the GND line wide.
The derating curve below is a data when mounted on a double-side board of copper foil thickness 35μm, copper foil area
100x100mm (both sides) and thickness of the board 1.6mm. The radiation characteristics will change depending on the
wiring, so please refer to the data.
The thermal characteristics for this converter will be largely influenced by the mounted board and the ambient condition. For
this reason, finally mount the converter into the device that will be actually mounted. And when it is operated at the maximum
ambient temperature of the equipment, be sure that the temperature of the board surface does not exceed 100°C.
