72. Output Derating Curve
The following Output Current vs. Ambient Temperature is a measurement data when mounting on our
evaluation PCB. The output derating curve is affected by the mounting board, the external components,
and the ambient conditions. Therefore, use it after confirming the case temperature when the power
supply operates with actual device does not exceed 110ºC (Temperature Measurement Point On The
Case). Moreover, use below 85ºC ambient temperature.
＊Evaluation PCB Specification
Size 150mm×70mm t = 1.6mm
Material FR4 （Double sided）
Copper 35μm
(3) Temperature Measurement Point on The Case
Confirm the temperature measurement point on the case of Fig.73 is below 110ºC.
Moreover, clear the hole at the center of the label, and measure the metal part when you measure the
case temperature.
