Datasheet

LM2675MX-ADJ/NOPB – 1A Adjustable Buck Switching Regulator IC

The LM2675MX-ADJ/NOPB is a high-efficiency 1A monolithic step-down (buck) DC-DC converter designed for superior performance and ease of use. Built with advanced LMDMOS technology, it integrates all essential active functions to create a compact, reliable, and cost-effective switching power supply. The regulator operates over a wide input voltage range and is available in fixed output versions (3.3V, 5V, 12V) as well as an adjustable version, allowing output customization based on design needs.

Operating at a fixed 260kHz switching frequency, the LM2675 enables the use of small-sized inductors and capacitors, reducing board area and overall component cost. With an efficiency exceeding 90%, it minimizes heat generation—often eliminating the need for external heat sinks. The built-in frequency compensation, fixed-frequency oscillator, and current-mode control ensure excellent line and load regulation with minimal external components, simplifying circuit design. Ideal for a variety of applications including industrial, automotive, and consumer power systems, the LM2675MX-ADJ/NOPB offers the perfect balance between performance, simplicity, and reliability in a compact SOIC-8 package.
