LM3492MH/NOPB TI LED Driver | 20-HTSSOP | 4.5V-65V Input, 1.5A Output

Product Overview

The LM3492MH/NOPB is a high-voltage, 1.5A buck LED driver from Texas Instruments, designed for constant current regulation in automotive and industrial lighting applications. It operates from an input voltage range of 4.5V to 65V, making it suitable for 12V, 24V, and 48V systems. The device integrates a low-side N-channel MOSFET and uses a hysteretic control scheme for fast transient response and simple compensation. The 20-HTSSOP package offers excellent thermal performance.
