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. Do not exceed the maximum power.

2. If neither voltage trim nor remote sense will be used, connect pin 3 to pin 4 and pin 5 to pin 6.

3. CAUTION: The converter will be permanently damaged if the 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.

4. When using remote sense for voltage compensation or when using remote sense for trim, the

output will drift over temperature. Contact Applications Engineering for more information at
