High current MOSFET driver  
Features  
Dual MOSFET driver for synchronous rectified  
converters  
High driving current for fast external MOSFET  
switching  
High frequency operation  
SO-8  
Integrated bootstrap diode  
Adaptive dead-time management  
Flexible gate-drive: 5V to 12V compatible  
Description  
L6741 is a flexible, high-frequency dual-driver  
specifically designed to drive N-channel  
MOSFETs connected in Synchronous-Rectified  
Buck topology. Combined with ST PWM  
controllers, the driver allows implementing  
complete voltage regulator solutions for modern  
high-current CPUs. L6741 embeds high-current  
drivers for both high-side and low-side  
MOSFETS. The device accepts flexible power  
supply (5V to 12V) to optimize the gate-drive  
voltage for High-Side and Low-Side maximizing  
the System Efficiency.  
High-impedance (HiZ) management for output  
stage shutdown  
Preliminary OV protection  
SO-8 package  
Applications  
High current VRM / VRD for Desktop / Server /  
Workstation CPUs  
High current DC / DC converters  
The Bootstrap diode is embedded saving the use  
of external diodes. Anti shoot-through  
management avoids high-side and low-side  
mosfet to conduct simultaneously and, combined  
with Adaptive Dead-Time control, minimizes the  
LS body diode conduction time.  
L6741 embeds Preliminary OV Protection: after  
Vcc overcomes the UVLO and while the device is  
in HiZ, the Low-Side MOSFET is turned ON to  
protect the load in case the output voltage  
overcomes a warning threshold protecting the  
load from High-Side MOSFET failures.  
The driver is available is SOP8 package.
