ISL6539
Pin 14, VIN
This pin connects to battery voltage, and is less noise
sensitive.
Copper Size for the Phase Node
Big coppers on both sides of the Phase node introduce
parasitic capacitance. The capacitance of PHASE should be
kept very low to minimize ringing. If ringing is excessive, it
could easily affect current sample information. It would be
best to limit the size of the PHASE node copper in strict
accordance with the current and thermal management of the
application.
Decoupling Capacitor for Switching MOSFET
It is recommended that ceramic caps be used closely
connected to the drain side of the upper MOSFET, and the
source of the lower MOSFET. This capacitor reduces the
noise and the power loss of the MOSFET. Refer to Figure 13
for the power component placement.

PGND2, should be closely connected to the power ground.
The other components should connect to signal ground.
Signal and power ground are tied together at the negative
terminal of the output capacitors.
