LM5575QMH/NOPB TI Switching Regulator | 16-HTSSOP | 75V Input, 0.5A Output

Product Overview

The LM5575QMH/NOPB is a high-voltage, 0.5A step-down switching regulator from Texas Instruments, designed for automotive and industrial applications. It operates over a wide input voltage range of 6V to 75V, making it suitable for 12V, 24V, and 48V systems. The device integrates a 75V N-channel MOSFET and uses a constant on-time (COT) control architecture for fast transient response and simple compensation. Housed in a 16-pin HTSSOP package with exposed pad for thermal dissipation, it offers high efficiency and reliability.
