Product Introduction

Overview

The LM5017SDE/NOPB is a 100-V, 600-mA synchronous stepdown regulator produced by Texas Instruments. This device is designed to provide efficient and reliable step-down regulation from high input voltages. It features integrated 100-V high-side and low-side MOSFETs, eliminating the need for external Schottky diodes. The LM5017 employs a constant on-time (COT) control scheme, which requires no loop compensation and offers ultra-fast transient response and nearly constant operating frequency. This regulator is well-suited for various industrial and communications applications, including 24-V industrial systems and 48-V communications systems.
