Description
L6743, L6743Q 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 and
DCDC conversion in general. L6743, L6743Q
embeds high-current drivers for both high-side
and low-side MOSFETS. The device accepts
flexible power supply (5 V to 12 V) to optimize the
gate-drive voltage for High-Side and Low-Side
maximizing the System Efficiency.
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.
L6743, L6743Q embeds Preliminary OV
Protection: after Vcc overcomes the UVLO and
while the device is in HiZ, the LS MOSFET is
turned ON to protect the load in case the output
voltage overcomes a warning threshold protecting
the output against HS failures.
The driver is available is SO-8 and DFN10 3x3
