ISL6605
FN9091.7
Synchronous Rectified MOSFET Driver
The ISL6605 is a high frequency, MOSFET driver optimized
to drive two N-Channel power MOSFETs in a synchronous-
rectified buck converter topology. This driver combined with
an Intersil HIP63xx or ISL65xx Multi-Phase Buck PWM
controller forms a complete single-stage core-voltage
regulator solution with high efficiency performance at high
switching frequency for advanced microprocessors.
The IC is biased by a single low voltage supply (5V) and
minimizes low driver switching losses for high MOSFET gate
capacitance and high switching frequency applications.
Each driver is capable of driving a 3000pF load with an 8ns
propagation delay and less than 10ns transition time. This
product implements bootstrapping on the upper gate with an
internal bootstrap Schottky diode, reducing implementation
cost, complexity, and allowing the use of higher
performance, cost effective N-Channel MOSFETs. Adaptive
shoot-through protection is integrated to prevent both
MOSFETs from conducting simultaneously.
The ISL6605 features 4A typical sink current for the lower
gate driver, which is capable of holding the lower MOSFET
gate during the Phase node rising edge to prevent shoot-
through power loss caused by the high dv/dt of the Phase
node.
The ISL6605 also features a Three-State PWM input that,
working together with Intersil multi-phase PWM controllers,
will prevent a negative transient on the output voltage when
the output is being shut down. This feature eliminates the
Schottky diode that is usually seen in a microprocessor
power system for protecting the microprocessor from
reversed-output-voltage damage.
