L6747A Overview
Description
The L6747A 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 Table 1.
Key Features
- The L6747A 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
- The embedded bootstrap diode eliminates the need for external diodes
- The L6747A features preliminary OV protection to protect the load from dangerous overvoltage due to MOSFET failures at startup
- The L6747A device is available in a VFDFPN8 3x3 mm package
