ISL6596
FN9240.2
Synchronous Rectified MOSFET Driver
The ISL6596 is a high frequency, MOSFET driver optimized
to drive two N-Channel power MOSFETs in a synchronous
buck converter topology. This driver combined with Intersil’s
Multi-Phase Buck PWM controllers 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),
minimizing driver switching losses in high MOSFET gate
capacitance and high switching frequency applications.
Each driver is capable of driving a 3nF load with less than
10ns rise/fall time. Bootstrapping of the upper gate driver is
implemented via an internal low forward drop 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 ISL6596 features 4A typical sink current for the lower
gate driver, enhancing the lower MOSFET gate hold-down
capability during PHASE node rising edge, preventing power
loss caused by the self turn-on of the lower MOSFET due to
the high dV/dt of the switching node.
The ISL6596 also features an input that recognizes a
high-impedance state, working together with Intersil
multi-phase 3.3V or 5V PWM controllers to prevent negative
transients on the controlled output voltage when operation is
suspended. This feature eliminates the need for the schottky
diode that may be utilized in a power system to protect the
load from negative output voltage damage.
