xinbole

The LM2575 series from Xinbole (LM2575-5.0, LM2575-12, and LM2575-ADJ) is a high-efficiency step-down (buck) switching voltage regulator designed for reliable DC-DC power conversion in industrial, automotive, and embedded electronic systems. Operating with an input voltage range up to 40V and delivering up to 1A output current, this IC provides stable and efficient power regulation with minimal external components, making it ideal for compact and cost-effective power supply designs.

Built using advanced switching regulator technology, the LM2575 integrates a fixed-frequency oscillator, internal power switch, and control circuitry for high-performance voltage conversion. While it does not directly incorporate Schottky diode technology internally, it is typically paired with an external Schottky rectifier diode to achieve fast switching performance, low forward voltage drop (low VF), reduced switching losses, and improved overall efficiency. This results in excellent thermal performance and high reliability even under continuous load conditions.

Compared to linear regulator series, the LM2575 offers significantly higher efficiency by minimizing power dissipation, especially in high input-to-output voltage difference applications. This makes it a superior solution for energy-efficient power supply designs.

Available in TO-220 and TO-263 package options, the LM2575 supports both through-hole and surface-mount PCB integration, providing flexibility for prototyping and mass production. It is widely used in DC-DC converters, embedded power supplies, automotive electronics, industrial control systems, and battery-powered devices. With its efficiency, simplicity, and robust performance, the Xinbole LM2575 series is a trusted solution for modern switching power design.
