Texas Instruments LM2675M-5.0 Step-Down Switching Regulator, 5V/1A, SOIC-8

The Texas Instruments LM2675M-5.0/NOPB is a highly efficient SIMPLE SWITCHER® step-down (buck) voltage regulator designed for simplicity and reliability. This integrated circuit provides all the necessary active functions to deliver a stable 5V output from a wider input voltage range, making it an excellent choice for a variety of power management applications. Its low external component count—requiring only five additional parts—significantly simplifies design and reduces overall system cost and board space.

Operating at a switching frequency of 260 kHz, this regulator allows for the use of smaller, more cost-effective filter components compared to lower-frequency alternatives. It features excellent line and load regulation, capable of driving a 1A load with consistent performance. The device includes patented internal frequency compensation and a fixed-frequency oscillator, ensuring stable operation under varying conditions.

Key Features & Protections

• High Efficiency & Integration: Combines a 0.25Ω DMOS output switch with control logic in a single package.
