L6743, L6743Q is a flexible, high-frequency dualdriver specifically designed to drive N-Channel MOSFETs connected in Synchronous-Rectified Buck topology.\nCombined 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 (5V to 12V) to optimize the gatedrive voltage for High-Side and Low-Side maximizing the System Efficiency.\nThe 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.\nL6743, 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.\nThe driver is available is SO8 and DFN10 3x3 packages.\n
