Advanced Synchronous Rectified Buck

MOSFET Drivers with Protection Features

Features

• Pin-to-pin Compatible with HIP6601 SOIC family for Better

Performance and Extra Protection Features

The ISL6612 and ISL6613 are high frequency MOSFET

drivers specifically designed to drive upper and lower power

N-Channel MOSFETs in a synchronous rectified buck

converter topology. These drivers combined with HIP63xx or

ISL65xx Multi-Phase Buck PWM controllers and N-Channel

MOSFETs form complete core-voltage regulator solutions for

advanced microprocessors.

• Dual MOSFET Drives for Synchronous Rectified Bridge

• Advanced Adaptive Zero Shoot-Through Protection

- Body Diode Detection

- Auto-zero of r

DS(ON)

Conduction Offset Effect

• Adjustable Gate Voltage (5V to 12V) for Optimal Efficiency

• 36V Internal Bootstrap Schottky Diode

The ISL6612 drives the upper gate to 12V, while the lower

gate can be independently driven over a range from 5V to

12V. The ISL6613 drives both upper and lower gates over a

range of 5V to 12V. This drive-voltage provides the flexibility

necessary to optimize applications involving trade-offs

between gate charge and conduction losses.

• Bootstrap Capacitor Overcharging Prevention

• Supports High Switching Frequency (up to 2MHz)

- 3A Sinking Current Capability

- Fast Rise/Fall Times and Low Propagation Delays

An advanced adaptive zero shoot-through protection is

integrated to prevent both the upper and lower MOSFETs

from conducting simultaneously and to minimize the dead

time. These products add an overvoltage protection feature

operational before VCC exceeds its turn-on threshold, at

which the PHASE node is connected to the gate of the low

side MOSFET (LGATE). The output voltage of the converter

is then limited by the threshold of the low side MOSFET,

which provides some protection to the microprocessor if the

upper MOSFET(s) is shorted during startup. The over-

temperature protection feature prevents failures resulting

from excessive power dissipation by shutting off the outputs

when its junction temperature exceeds +150°C (typically).

The driver resets once its junction temperature returns to

+108°C (typically).

• Three-State PWM Input for Output Stage Shutdown

• Three-State PWM Input Hysteresis for Applications With

Power Sequencing Requirement

• Pre-POR Overvoltage Protection

• VCC Undervoltage Protection

• Over Temperature Protection (OTP) with +42°C

Hysteresis

• Expandable Bottom Copper Pad for Enhanced Heat

Sinking

• Dual Flat No-Lead (DFN) Package

- Near Chip-Scale Package Footprint; Improves PCB

Efficiency and Thinner in Profile

• Pb-Free Plus Anneal Available (RoHS Compliant)

These drivers also feature a three-state PWM input which,

working together with Intersil’s multi-phase PWM controllers,

prevents a negative transient on the output voltage when the

output is shut down. This feature eliminates the Schottky

diode that is used in some systems for protecting the load

from reversed output voltage events.

Applications

• Core Regulators for Intel® and AMD® Microprocessors

• High Current DC/DC Converters

• High Frequency and High Efficiency VRM and VRD

Processing Moisture Sensitive Surface Mount Devices

(SMDs)”

Guidelines, and Feedback Compensation Design

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