Sense Kelvin connection which allows remote sensing of the output voltage for im-
proved regulation. If remote sensing is not required, connect to VOUT.
*Pin 6 GND is not directly shorted to the fused paddle GND. The fused paddle GND (pins 4, 5, 12, 13) is connected through the substrate.
Pin 6 must be electrically connected to at least one of the fused paddle GND’s on the PC board.
