pin and the GND pin (which connects to the signal ground
plane). The output current is sensed (as a voltage) by the
CS+ and CS– pins. In order to avoid differential mode
noise pickup in the sensed signal, the loop area should be
small. Thus the FB trace should be routed atop the signal
ground plane, and the CS+ and CS– pins should be routed
as a closely coupled pair (the CS+ pin should be over the
signal ground plane as well).
