FAN53418

Synchronous DC-DC MOSFET Driver

Features

General Description

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

a synchronous buck conﬁguration

• Internal Adaptive “Shoot-Through” Protection

• High Switching Frequency (> 500kHz)

– 30ns Output Rise/Fall Times w/3000pF load

– 20ns Propagation Delay

The FAN53418 is a high frequency, dual MOSFET driver

speciﬁcally designed to drive two power N-Channel

MOSFETs in a synchronous rectiﬁed buck converter.

These drivers combined with a FAN53168 Multi-Phase Buck

PWM controller and power MOSFETs form a complete core

voltage regulator solution for advanced microprocessors.

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

• OD input for Output Disable – allows for synchronization

with PWM controller

The FAN53418 drives both the upper and lower gates in a

synchronous rectiﬁer to +12V. The upper gate drive imple-

ments bootstrapping with only an external capacitor and

diode required. This reduces implementation complexity

and allows the use of higher performance, cost effective,

N-Channel MOSFETs.

• SOIC-8 Package

Applications

• Multi-phase VRM/VRD regulators for Microprocessor

Power

• High Current/High Frequency DC/DC Converters

• High Power Modular Power Supplies

The output drivers in the FAN53418 have the capacity to

efﬁciently switch power MOSFETs at frequencies over

500kHz. Each driver is capable of driving a 3000pF load

with a ~20ns propagation delay and ~30ns transition time.

Adaptive shoot-through protection is integrated to prevent

both MOSFETs from conducting simultaneously. Addition-

ally an Output Disable function is included to synchronize

the driver with the PWM controller. The FAN53418 is

rated for operation from 0°C to +85°C and is available in a

low-cost SOIC-8 package.
