  • L6743B 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 DC-DC conversion in general. L6743B embeds high-current drivers for both high-side andlow-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.
    L6743B 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 VFDFPN8 3 x 3 mm packages.
