REMOTE SENSE APPLCIATION CIRCUIT The Remote Sense function is used to compensate for the voltage drop incurred when the load is located physical far away from the DC/DC converter providing its power. The Remote Sense pins are connected as close to the load as possible. The DC/DC converter’s regulation specification is maintained across the points where the Remote Sense wires are connected at the load. This will remove the effect of the voltage drop caused by the resistance of the wires used to conduct the power from the DC/DC converter to the load. This is represented by RCL1 and RCL2. With the use of Remote Sense, the effects of RCL1 and RCL2 are eliminated. If Remote Sense function is not used, the +Sense has to be connected to the +Vout and the –Sense has to be connected to –Vout as close to the DC/DC converter as possible

The bandwidth is 0-20MHz Output Ripple & Noise measurement test circuit: as shown below. 9. Temperature Derating Curve: The DC-DC converter will operate over a wider temperature range if less power is drawn from the output and 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.
