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.
Ambient Temp.TA (℃)
10. Switching frequency: The nominal operating frequency of the DC-DC converters.
11. Input to output isolation: The dielectric breakdown strength test between input and output circuits. This is the
isolation voltage the device is capable of withstanding for a specified time, usually 1 second or 1 minute.
