Product Details

Our advantages

Chinese manufacturing processes have undergone years of iteration, resulting in mature and reliable technologies. Many international corporations opt for production outsourcing in China. As an electronic components manufacturer in China, our products can fully replace those of major international brands in 99% of applications without the need for testing verification. Our products boast high consistency in quality, reasonable pricing, ample inventory, flexible supply, short lead times, and professional after-sales service.

Description

The LM2596/LM2596HV is a PWM DC-DC buck regulator with a fixed frequency of 150 kHz.It features a 3A output current capability, high efficiency, low ripple, and excellent linearity in both line and load regulation. The chip uses PWM modulation, allowing the duty cycle to be adjusted linearly in the range of 0-100%. The LM2596/LM2596HV integrates a fixed-frequency oscillator and a frequency compensation module, making it very easy to use with minimal external components. Additionally, it includes several built-in protection features, such as enable with hysteresis, over-temperature protection, over-current protection, and latch-off over-current protection. In the event of secondary over-current protection,the chip automatically reduces the operating frequency from 150 kHz to 50 kHz.
