Notes for Remote Sense and Trim
1. When trimming output voltage and/or remote sensing, the total output
voltage increase must be less than 0.6 volts at the converters pins to
maintain specified performance.
2. If neither voltage trim nor remote sense will be used, connect pin 3 to
pin 4 and pin 5 to pin 6 or the output voltage will increase by 1.2 volts.
3. CAUTION: The converter will be permanently damaged if the positive
remote sense (pin 6) is shorted to ground. Damage may also result if
the output common or positive output is disconnected from the load with
the remote sense leads connected to the load.
