ISL6597
Data Sheet
May 4, 2007
FN9165.1
Dual Synchronous Rectified MOSFET
Drivers
The ISL6597 integrates two ISL6596 drivers and is
optimized to drive two independent power channels in a
synchronous-rectified buck converter topology. These
drivers, combined with an Intersil multiphase PWM
controller, form a complete high efficiency voltage regulator
solution.
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 ISL6597 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 ISL6597 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.

material sets; molding compounds/die attach materials and 100%
matte tin plate termination finish, which are RoHS compliant and
compatible with both SnPb and Pb-free soldering operations. Intersil
Pb-free products are MSL classified at Pb-free peak reflow
temperatures that meet or exceed the Pb-free requirements of
IPC/JEDEC J STD-020.
