The LM2576HVS Step Down Module is a technically sophisticated DC-to-DC buck converter, optimized for high-input voltage scenarios ranging from 5V to 60V. It offers a versatile and precise output voltage control, with a customizable range of 1.25V to 30V, courtesy of its onboard multi-turn potentiometer. This module excels in voltage regulation, with an emphasis on efficiency and reliability, making it suitable for various applications such as automotive electronics, solar power systems, and battery charging.
The LM2576 series of regulators are monolithic integrated circuits that provide all the active functions for a step-down (buck) switching regulator, capable of driving a 3-A load with excellent line and load regulation. These devices are available in fixed output voltages of 3.3 V, 5 V, 12 V, and 15 V, and an adjustable output version.
