ST L6741 handbook(1)

Update: 29 September, 2023

The L6741 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. The L6741 embeds high-current drivers for both high-side and low-side MOSFETs. The device accepts flexible power supply (5V to 12V) to optimize the gate-drive voltage for high-side and low-side, maximizing system efficiency. The Bootstrap diode is embedded, saving the use of external diodes. Anti shoot-through management avoids high-side and low-side MOSFETs conducting simultaneously, and combined with Adaptive Dead-Time control, minimizes the low-side body diode conduction time. The L6741 embeds preliminary overvoltage protection: after Vcc overcomes the undervoltage lockout and while the device is in high-impedance mode, the low-side
