Synchronous Rectified MOSFET Driver

Features

• Drives Two N-Channel MOSFETs

The ISL6609, ISL6609A 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 ISL63xx or ISL65xx multiphase

PWM controller forms a complete single-stage core-voltage

regulator solution with high efficiency performance at high

switching frequency for advanced microprocessors.

• Adaptive Shoot-Through Protection

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

• Supports High Switching Frequency

- Fast Output Rise and Fall

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

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.

• ISL6605 Replacement with Enhanced Performance

• BOOT Capacitor Overcharge Prevention (ISL6609A)

• Low V Internal Bootstrap Diode

• Low Bias Supply Current

• Enable Input and Power-On Reset

• QFN Package

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

No Leads-Product Outline

The ISL6609, ISL6609A 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.

- Near Chip-Scale Package Footprint; Improves PCB

Efficiency and Thinner in Profile

• Pb-Free Plus Anneal Available (RoHS Compliant)

Applications

• Core Voltage Supplies for Intel® and AMD®

Microprocessors

The ISL6609, ISL6609A also features an input that

recognizes a high-impedance state, working together with

Intersil multiphase 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. In addition, the

ISL6609A’s bootstrap function is designed to prevent the

BOOT capacitor from overcharging, should excessively large

negative swings occur at the transitions of the PHASE node.

• High Frequency Low Profile High Efficiency DC/DC

Converters

• High Current Low Voltage DC/DC Converters

• Synchronous Rectification for Isolated Power Supplies

Processing Moisture Sensitive Surface Mount Devices
