LM2596SX/LM2596HV is a fixed frequency PWM DCDCvoltage stabilizing power converter with fixed frequency of 150KHz. With the 3A output current driving ability, it has characteristics such as high efficiency, low ripple wave, high linear adjustment rate and load regulation. With the PWM modulation mode, the chip can adjust the linear ranges of the duty ratio of 0-100%.
LM2596SX/LM2596HV has a built-in fixed frequency oscillator and a frequency compensation module, with simple use, and only a small number of external components and parts are needed. In addition, the chip has built-in functions such as enabling, over-temperature protection, over-current protection and stimulation over current protection with the hysteresis function. In condition of secondary over-current protection, the built-in downconversion function can reduce the working frequency from 150KHz to 50KHz.

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.
