L6747A - High Current MOSFET Driver

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.

Features
