ISL6265C
PGND PINS
This is the return path for the pull-down of the LGATE low-side
MOSFET gate driver. Ideally, PGND should be connected to the
source of the low-side MOSFET with a low-resistance, low-
inductance path.
VIN PIN
The VIN pin should be connected close to the drain of the high-
side MOSFET, using a low- resistance and low-inductance path.
VCC PIN
For best performance, place the decoupling capacitor very close
to the VCC and GND pins.
PVCC PIN
For best performance, place the decoupling capacitor very close
to the PVCC and respective PGND pins, preferably on the same
side of the PCB as the ISL6265C IC.
ENABLE AND PGOOD PINS
These are logic signals that are referenced to the GND pin. Treat
as a typical logic signal.
FB PINS
The input impedance of the FB pin is high, so place the voltage
programming and loop compensation components close to the
COMP, FB, and GND pins keeping the high impedance trace
short.
25
FSET_NB PIN
This pin requires a quiet environment. The resistor R FSET should
be placed directly adjacent to this pin. Keep fast moving nodes
away from this pin.
LGATE ROUTING
The LGATE trace has a signal going through it that is both high
dV/dt and di/dt, with high peak charging and discharging
current. Route this trace in parallel with the trace from the PGND
pin. These two traces should be short, wide, and away from other
traces. There should be no other weak signal traces in proximity
with these traces on any layer.
BOOT AND PHASE ROUTING
The signals going through these traces are both high dv/dt and
high di/dt, with high peak charging and discharging current.
Route the UGATE and PHASE pins in parallel with short and wide
traces. There should be no other weak signal traces in proximity
with these traces on any layer.
Copper Size for the Phase Node
The parasitic capacitance and parasitic inductance of the phase
node should be kept very low to minimize ringing. It is best to
limit the size of the PHASE node copper in strict accordance with
the current and thermal management of the application. An
MLCC should be connected directly across the drain of the upper
MOSFET and the source of the lower MOSFET to suppress the
turn-off voltage.
