Description

The L6747C 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 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 low-

side 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.
