● Dual MOSFET driver for synchronous rectified converters High driving current for fast external MOSFET switching Integrated bootstrap diode High frequency operation Enable pin Adaptive dead-time management Flexible gate-drive: 5 V to 12 V compatible High-impedance (HiZ) management for output stage shutdown Preliminary OV protection SO8 package Combined with ST PWM controllers, the driver allows implementing complete voltage regulator solutions for modern high-current CPUs and DCDC conversion in general. L6743D embeds high-current drivers for both high-side and lowside MOSFETS. The device accepts flexible power supply (5 V to 12 V) to optimize the gatedrive 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.
