LM3485MMX/NOPB TI Switching Controller | 8-VSSOP | 4.5V-35V, 1A

Product Overview

The LM3485MMX/NOPB is a high-performance switching controller from Texas Instruments, designed for step-down (buck) regulator applications. 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 device integrates a high-side N-channel MOSFET and provides excellent line and load regulation. The LM3485MMX/NOPB features current-mode control for fast transient response and includes built-in protection features such as thermal shutdown, overcurrent protection, and undervoltage lockout. Its high efficiency and small footprint make it ideal for space-constrained power supply designs.
