ISL6208CRZ规格书详情
The ISL6208 and ISL6208B are high frequency, dual MOSFET
drivers, optimized to drive two N-Channel power MOSFETs in a
synchronous-rectified buck converter topology. They are
especially suited for mobile computing applications that
require high efficiency and excellent thermal performance.
These drivers, combined with an Intersil multiphase Buck
PWM controller, form a complete single-stage core-voltage
regulator solution for advanced mobile microprocessors.
ISL6208 and ISL6208B have the same function but different
packages. The descriptions in this datasheet are based on
ISL6208 and also apply to ISL6208B.
The ISL6208 features 4A typical sinking current for the lower
gate driver. This current is capable of holding the lower
MOSFET gate off during the rising edge of the Phase node. This
prevents shoot-through power loss caused by the high dv/dt of
phase voltages. The operating voltage matches the 30V
breakdown voltage of the MOSFETs commonly used in mobile
computer power supplies.
The ISL6208 also features a three-state PWM input that,
working together with Intersil’s multiphase PWM controllers,
will prevent negative voltage output during CPU shutdown. This
feature eliminates a protective Schottky diode usually seen in
a microprocessor power systems.
MOSFET gates can be efficiently switched up to 2MHz using
the ISL6208. Each driver is capable of driving a 3000pF load
with propagation delays of 8ns and transition times under
10ns. Bootstrapping is implemented with an internal Schottky
diode. This reduces system cost and complexity, while allowing
the use of higher performance MOSFETs. Adaptive shootthrough protection is integrated to prevent both MOSFETs from
conducting simultaneously.
A diode emulation feature is integrated in the ISL6208 to
enhance converter efficiency at light load conditions. This
feature also allows for monotonic start-up into pre-biased
outputs. When diode emulation is enabled, the driver will allow
discontinuous conduction mode by detecting when the
inductor current reaches zero and subsequently turning off the
low side MOSFET gate.
