Note:
10. See Basic Operation and feature section for the recommended/ appropriate Module Enable configuration.
11. The sense pins can be used to compensate for any voltage drops (per indicated max limits) that may
occur along the connection between the output pins to the load. Pin 7 (+Sense) and Pin 5
(-Sense) should be connected to Pin 8 (+Vout) and Pin 4 (Return) respectively at the point where
regulation is desired.
12. Refer to Equation (1) and (2) and Figures 3 and 4 for the Output Trim Adjust configuration.
13. The combination of remote sense and Trim adjust cannot exceed 110% of VO, NOM.
