| 15 | NC | unconnected | Listed as no connect in the pin table with no electrical function given. |
| 16 | FB | input | Output voltage feedback; the internal reference is 1.0 V (0.98 V to 1.02 V) and absolute maximum FB to GND is -0.3 V to 6 V. |
| 17 | CSP | input | Positive pole of the current sense; CSP-CSN current sense amplifier threshold is 51 mV to 59 mV and absolute maximum CSP to GND is -0.3 V to 25 V. |
| 18 | CSN1 | input | Negative pole 1 of the current sense; CSP-CSN1 threshold is 51 mV to 59 mV and absolute maximum CSN1 to GND is -0.3 V to 25 V. |
