LM3489MM/NOPB TI DC-DC Controller | 8-VSSOP | 4.5V-35V Input, 1A Output

Product Overview

The LM3489MM/NOPB is a high-performance, non-synchronous buck (step-down) DC-DC controller from Texas Instruments. It is designed to drive an external N-channel MOSFET and provides a compact, efficient solution for converting input voltages from 4.5V to 35V down to an adjustable output voltage as low as 1.26V. Housed in an 8-pin VSSOP package, this controller integrates a high-side bootstrap diode and offers features such as cycle-by-cycle current limiting, thermal shutdown, and undervoltage lockout. With its wide input range and high efficiency, the LM3489MM/NOPB is ideal for a variety of applications including industrial power supplies, automotive systems, and telecommunications equipment.
