Datasheet

LM2594MX-ADJ/NOPB – Buck Switching Regulator IC 500mA SOIC-8

The LM2594MX-ADJ/NOPB from Texas Instruments is a versatile, monolithic step-down (buck) switching regulator designed to deliver up to 500mA of continuous output current with excellent line and load regulation. This adjustable version supports a wide output voltage range, making it suitable for various power management applications in industrial, automotive, and embedded systems. Operating at a fixed switching frequency of 150kHz, the LM2594 provides a stable, efficient, and compact solution requiring only a few external components. The device features internal frequency compensation and a fixed-frequency oscillator, simplifying circuit design and ensuring predictable performance. With a broad input voltage range (4V to 40V for standard versions; up to 60V for HV models), it is ideal for use with unregulated DC sources such as batteries or adapters.

The LM2594 incorporates overcurrent protection, thermal shutdown, and a two-stage current limit, ensuring robust and reliable operation even under fault conditions. Additionally, it offers external shutdown control with a low 85uA standby current, helping to extend battery life in portable systems. Available in a compact 8-pin SOIC package, the LM2594 provides a cost-effective and space-efficient DC-DC power conversion solution.
