FAN5009

Dual Bootstrapped 12V MOSFET Driver

Features

General Description

• Drives N-channel High-Side and Low-Side MOSFETs in

a synchronous buck conﬁguration

• 12V High-Side and 12V Low-Side Drive

• Internal Adaptive “Shoot-Through” Protection

• Integrated Bootstrap Diode for High-Side Drive

• Fast rise and fall times

The FAN5009 is a dual, high frequency MOSFET driver,

speciﬁcally designed to drive N-Channel power MOSFETs

in a synchronous-rectiﬁed buck converter. These drivers,

combined with a Fairchild Multi-Phase PWM controller and

power MOSFETs, form a complete core voltage regulator

solution for advanced microprocessors.

• Switching Frequency Up to 500kHz

• OD input for Output Disable – allows for synchronization

with PWM controller

• SOIC-8 Package

• Available in low thermal resistance MLP package

The FAN5009 drives the upper and lower MOSFET gates of

a synchronous buck regulator to 12V_GS. The upper gate

drive includes an integrated boot diode and requires only an

external bootstrap capacitor (C_BOOT). The output drivers in

the FAN5009 have the capacity to efﬁciently switch power

MOSFETs at frequencies up to 500kHz. The circuit’s

adaptive shoot-through protection prevents the MOSFETs

from conducting simultaneously.

Applications

• Multi-phase VRM/VRD regulators for Microprocessor

Power

• High Current/High Frequency DC/DC Converters

• High Power Modular Supplies

The FAN5009 is rated for operation from 0°C to +85°C and

is available in low-cost SOIC-8 or MLP packages.
