Additional Infomation About Product

L6743 L6743Q High current MOSFET driver Features Dual MOSFET driver for synchronous rectified converters High driving current for fast external MOSFET switching SO-8 DFN10 3x3 Integrated bootstrap diode High frequency operation Combined with ST PWM controllers, the driver Enable pin allows implementing complete voltage regulator solutions for modern high-current CPUs and Adaptive dead-time management DCDC conversion in general. L6743, L6743Q Flexible gate-drive: 5 V to 12 V compatible embeds high-current drivers for both high-side High-impedance (HiZ) management for output and low-side MOSFETS. The device accepts stage shutdown flexible power supply (5 V to 12 V) to optimize the gate-drive voltage for High-Side and Low-Side Preliminary OV protection maximizing the System Efficiency. SO-8 and DFN10 3x3 packages The Bootstrap diode is embedded saving the use of external diodes. Anti shoot-through Applications management avoids high-side and low-side MOSFET to conduct simultaneously and, High current VRM / VRD for desktop / server / combined with Adaptive Dead-Time control, workstation CPUs minimizes the LS body diode conduction time. High current and high efficiency DC / DC converters L6743, L6743Q embeds Preliminary OV Protection: after Vcc overcomes the UVLO and while the device is in HiZ, the LS MOSFET is Description turned ON to protect the load in case the output voltage overcomes a warning threshold protecting L6743, L6743Q is a flexible, high-frequency dual- the output against HS failures. driver specifically designed to drive N-channel MOSFETs connected in synchronous-rectified The driver is available is SO-8 and DFN10 3x3 buck topology. packages Table 1.
