Copper strip DC/DC converter Co Oscilloscope Load Copper strip 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. 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. E-mail: [email protected] http://www.bothhandusa.com Rev:20150617A Page 8 of 8
