Thermal Management
For maximum thermal performance in high current, high
switching frequency applications, connecting the thermal
GND pad of the ISL6566 to the ground plane with multiple
vias is recommended. This heat spreading allows the part to
achieve its full thermal potential. It is also recommended
that the controller be placed in a direct path of airflow if
possible to help thermally manage the part.
Suppressing MOSFET Gate Leakage
With VCC at ground potential, UGATE is high impedance. In
this state, any stray leakage has the potential to deliver
charge to the gate of the upper MOSFET. If UGATE receives
sufficient charge to bias the device on, a low impedance path
will be connected between the upper MOSFET drain and
PHASE. If this occurs and the input power supply is present
and active, the system could see potentially damaging
current. Worst-case leakage currents are on the order of
pico-amps; therefore, a 10k
resistor, connected from
UGATE to PHASE, is more than sufficient to bleed off any
stray leakage current. This resistor will not affect the normal
performance of the driver or reduce its efficiency.
