LM2588S-ADJ/NOPB

The LM2588S-ADJ/NOPB is a monolithic step-up flyback switching regulator from Texas Instruments’ SIMPLE SWITCHER® family, integrating a 5 A internal power switch and a wide 4 V to 40 V input voltage range. This adjustable-output device operates in flyback topology, enabling generation of isolated or non-isolated supply rails that can be higher, lower, or inverting relative to the input. A dedicated frequency synchronization pin allows locking the switching frequency to an external clock signal, reducing interference in noise-sensitive analog and mixed-signal systems. Comprehensive internal protection features include cycle-by-cycle current limiting, thermal shutdown, and undervoltage lockout, all enclosed in a thermally efficient TO-263 power package.

Typical end uses span isolated power supplies for industrial automation controllers, distributed power architectures in telecom infrastructure, and bias voltage generation for motor drives and fieldbus interfaces. The wide input capability also supports automotive and avionics power conditioning modules that must tolerate substantial input transients. Procurement engineers view the LM2588S-ADJ/NOPB as an active, industrial-grade component with RoHS compliance and a standard surface-mount footprint. As part of the SIMPLE SWITCHER product line, it benefits from Texas Instruments’ long-lifecycle support strategy, reducing redesign risk for high-reliability equipment requiring sustained availability.
