Dual Synchronous Rectified MOSFET

Drivers

Features

• 5V Quad N-Channel MOSFET Drives for Two

Synchronous Rectified Bridges

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.

• Adaptive Shoot-Through Protection

• Programmable Deadtime for Efficiency Optimization

• Diode Emulation for Efficiency and Pre-Biased Startup

• 0.4Ω On-Resistance and 4A Sink Current Capability

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.

• Supports High Switching Frequency

- Fast Output Rise and Fall

- Ultra Low Tri-State Hold-Off Time (20ns)

• Low V Internal Bootstrap Diode

• Low Bias Supply Current

• Support 3.3V and 5V PWM Input

• Enable Input and Power-On Reset

• QFN Package

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.

- Compliant to JEDEC PUB95 MO-220 QFN-Quad Flat

No Leads-Product Outline

- Near Chip-Scale Package Footprint; Improves PCB

Utilization and Thinner in Profile

• Pb-Free Plus Anneal Available (RoHS Compliant)

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.

Applications

• Core Voltage Supplies for Intel® and AMD®

Microprocessors

• High Frequency Low Profile High Efficiency DC/DC

Converters

• High Current Low Voltage DC/DC Converters

NOTE: Intersil Pb-free plus anneal products employ special Pb-free

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.

CAUTION: These devices are sensitive to electrostatic discharge; follow proper IC Handling Procedures.
