Product Introduction

Overview

The LM5002SDX/NOPB, produced by Texas Instruments, is a high-voltage switch mode regulator designed to implement efficient high-voltage boost, flyback, SEPIC, and forward converters. This regulator integrates a 75-V N-channel MOSFET with a 0.5-A peak current limit, making it suitable for a wide range of applications. It features current mode control, which provides simple loop compensation and line-voltage feed-forward, and includes various protection mechanisms such as cycle-by-cycle current limiting and thermal shutdown.
