IL2576-ADJ2T IC – IKSemi – 3A Step-Down Switching Regulator – TO263-5 – LM2596-ADJ Alternate

The IL2576 Adjustable Version is a versatile and efficient step-down switching regulator designed to cater to a wide range of power supply applications. Capable of driving a 3.0 A load, this regulator offers an adjustable output voltage ranging from 1.23V to 37V, making it suitable for both simple and complex power management systems. The IL2576 operates with a fixed 52 kHz internal oscillator, requiring only four external components to build a reliable and efficient power supply. Its high efficiency and minimal power dissipation often eliminate the need for a heatsink, enabling more compact designs. The regulator’s robust protection features include thermal shutdown, cycle-by-cycle current limiting, and a low standby current of 80 µA, making it ideal for energy-conscious applications.

Designed for flexibility and reliability, the IL2576 is available in TO-220-5L and TO-263-5L packages, making it easy to integrate into various circuit designs. The regulator’s wide input voltage range, 3.0 A output current, and compatibility with standard inductors further simplify the design process. Whether used as a simple high-efficiency step-down regulator, an efficient pre-regulator for linear regulators, or in applications like on-card switching, battery chargers, or negative step-up converters, the IL2576 Adjustable Version delivers dependable performance with adjustable voltage output for precise control.
