L6747A  
High current MOSFET driver  
Features  
Dual MOSFET driver for synchronous rectified  
converters  
High driving current for fast external MOSFET  
switching  
Integrated bootstrap diode  
High frequency operation  
Enable pin  
VFDFPN8 3x3 mm  
regulator solutions for modern high-current CPUs  
and for DC-DC conversion in general.  
Adaptive dead-time management  
Flexible gate-drive: 5 V to 12 V compatible  
The L6747A embeds high-current drivers for both  
high-side and low-side MOSFETS. The device  
accepts a flexible power supply of 5 V to 12 V.  
This allows optimization of the high-side and low-  
side gate-drive voltage to maximize system effi-  
ciency.  
High-impedance (HiZ) management for output  
stage shutdown  
Preliminary overvoltage (OV) protection  
VFDFPN8 3x3 mm package  
The embedded bootstrap diode eliminates the  
need for external diodes. Anti shoot-through man-  
agement prevents the high-side and low-side  
MOSFETs from conducting simultaneously and,  
combined with adaptive dead-time control, mini-  
mizes the LS body diode conduction time.  
Applications  
High current VRM / VRD for desktop / server /  
workstation CPUs  
High current and high efficiency DC-DC  
The L6747A features preliminary OV protection to  
protect the load from dangerous overvoltage due  
to MOSFET failures at startup.  
converters  
Description  
The L6747A device is available in a VFDFPN8  
3x3 mm package.  
The L6747A 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 the implementation of complete voltage
