Additional Infomation About Product

L6743D High current MOSFET driver Features Dual MOSFET driver for synchronous rectified converters High driving current for fast external MOSFET switching Integrated bootstrap diode SO8 High frequency operation Enable pin Adaptive dead-time management Combined with ST PWM controllers, the driver allows implementing complete voltage regulator Flexible gate-drive: 5 V to 12 V compatible solutions for modern high-current CPUs and High-impedance (HiZ) management for output DCDC conversion in general. L6743D embeds stage shutdown high-current drivers for both high-side and low- Preliminary OV protection side MOSFETS. The device accepts flexible power supply (5 V to 12 V) to optimize the gate- SO8 package drive voltage for high-side and low-side maximizing the system efficiency. Applications The bootstrap diode is embedded saving the use High current VRM / VRD for desktop / server / of external diodes. Anti shoot-through workstation CPUs management avoids high-side and low-side MOSFET to conduct simultaneously and, High current and high efficiency DC / DC combined with adaptive dead-time control, converter minimizes the LS body diode conduction time. L6743D embeds preliminary OV protection: after Vcc overcomes the UVLO and while the device is Description in HiZ, the LS MOSFET is turned ON to protect the load in case the output voltage overcomes a L6743D is a flexible, high-frequency dual-driver warning threshold protecting the output against specifically designed to drive N-channel HS failures. MOSFETs connected in synchronous-rectified buck topology. The driver is available is SO8 package. Table 1.
