L6747C：High current MOSFET driver
The L6747C is a flexible, high-frequency dualdriver specifically designed to drive N-channel MOSFETs connected in synchronous-rectified buck topology.
Combined with ST PWM controllers, the driver allows the implementation of complete voltage regulator solutions for modern high-current CPUs and for DC-DC conversion in general.
The L6747C embeds high-current drivers for both high-side and low-side MOSFETS. The device accepts a flexible power supply of 5 V to 12 V.
This allows optimization of the high-side and lowside gate-drive voltage to maximize system efficiency.
Anti shoot-through management prevents the high-side and low-side MOSFETs from conducting simultaneously and, combined with adaptive dead-time control, minimizes the LS body diode conduction time.
The L6747C features preliminary OV protection to protect the load from dangerous overvoltage due to MOSFET failures at startup.
The driver is available in a VFDFPN8 3x3 mm package.
