Introduction

AI Translation

LM2596SX/LM2596HV is a 150KHz fixed-frequency PWM DC-DC switching regulator. It features 3A output current drive capability, high efficiency, low ripple, and excellent line and load regulation. The device employs PWM modulation mode with a linearly adjustable duty cycle range of 0~100%.

The LM2596SX/LM2596HV integrates a fixed-frequency oscillator and frequency compensation module, making it extremely easy to use with only a minimal number of external components. In addition, the device incorporates enable with hysteresis, over-temperature protection, overcurrent protection, and secondary overcurrent protection. When secondary overcurrent protection is triggered, the built-in frequency reduction function reduces the operating frequency from 150KHz to 50KHz.
