Product Introduction

Overview

The NCP81075DR2G, 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 and features an on-chip bootstrap diode, eliminating the need for an external discrete diode. The NCP81075DR2G supports high floating top driver designs, accommodating boost voltages up to 180 V, and ensures independent control over the high-side and low-side drivers with precise delay matching.
