LM3489QMM/NOPB TI DC-DC Controller | 8-VSSOP | 4.5V-35V Input, 1A Output

Product Overview

The LM3489QMM/NOPB is a high-performance, non-synchronous buck controller from Texas Instruments, designed for step-down DC-DC conversion. It operates over a wide input voltage range of 4.5V to 35V and delivers up to 1A output current. Housed in a compact 8-VSSOP package, this controller integrates a high-side N-channel MOSFET driver and requires minimal external components. Its constant on-time (COT) control architecture provides fast transient response and stable operation with low ESR output capacitors. The device is qualified for automotive applications (AEC-Q100) and is ideal for powering sensitive loads in industrial, automotive, and telecom systems.
