FAN5109

Dual Bootstrapped 12V MOSFET Driver

Features

General Description

■ Drives N-channel High-Side and Low-Side MOSFETs

in a Synchronous Buck Conﬁguration

The FAN5109 is a high-frequency driver, speciﬁcally

designed to drive N-Channel power MOSFETs in a syn-

chronous-rectiﬁed buck converter. This driver, combined

with a Fairchild Multi-Phase PWM controller and power

MOSFETs, form a complete core voltage regulator solu-

tion for advanced microprocessors.

■ Enhanced Upgrade to FAN5009

■ Direct Interface to FAN5019B/FAN5182 and other

compatible PWM Controllers

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

■ Internal Adaptive “Shoot-Through” Protection

■ Fast Rise and Fall times

The FAN5109 drives the upper and lower MOSFET gates

of a synchronous buck regulator up to 12V . The

FAN5109’s output drivers can efﬁciently switch power

MOSFETs at frequencies above 500kHz. The circuit’s

adaptive shoot-through protection prevents the MOSFETs

from conducting simultaneously.

■ Switching Frequency above 500kHz

■ OD input for Output Disable – allows for synchroni-

zation with PWM Controller

■ SOIC-8 Package

The FAN5109 is rated for operation from 0°C to +85°C

and is available in a low-cost SOIC-8 package.

Applications

■ Multi-phase VRM/VRD Regulators for Microprocessor

Power

■ High Current/High Frequency DC/DC Converters

■ High Power Modular Supplies
