Product Introduction

Overview

The NCP81075MNTXG, produced by onsemi, is a high-performance dual MOSFET gate driver designed to drive the gates of both high-side and low-side power MOSFETs in synchronous buck converter topologies. This device is optimized for high-frequency switching applications, offering robust performance and reliability. The NCP81075MNTXG integrates an on-chip bootstrap diode, eliminating the need for an external discrete diode, and features a high floating top driver that can accommodate boost voltages up to 180 V.
