Note

1.At maximum output power, nominal input voltage,  Ta = 25°C.

2.Refer to Output Derating Curve (next page) for details of output derating versus input voltage,ambient temperature and mounting method .

3.Refer to picture A for measure results about line regulation,load regulation and ripple & noise

  Ripple & noise are measured at 20MHz by using a twisted pair of load wires terminated with a 0.1uF and 47uF capacitor.
