● 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: 5V to 12V compatible High-impedance (HiZ) management for output stage Shutdown Preliminary OV protection SO-8 and DFN10 3x3 packages SO-8 DFN10 3x3 Combined with ST PWM Controllers, the driver allows implementing complete voltage regulator solutions for modern high-current CPUs and DCDC conversion in general. L6743, L6743Q 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 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.
