Output Ripple&Noise measurement test circuit: as shown below.

Co: usually 0.47uF.

9. Temperature derating curve: The DC-DC converter will operate over a wider

temperature range if less power is drawn from the output and the device is

already running. The temperature derating curve shows the operating

power-temperature range. As shown below.

10. Switching frequency: The nominal operating frequency of the DC-DC converters.

and output circuits. This is the isolation voltage the device is capable of

withstanding for a specified time, usually 1 second or 1 minute.
