Overview

The LM2596SX/LM2596HV is a 150KHz fixed-frequency PWM DC-DC switching voltage regulator featuring 3A output current drive capability, high efficiency, low ripple, and excellent line and load regulation. The device operates in 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, requiring minimal external components for a simple implementation. Additional features include enable with hysteresis, over-temperature protection, overcurrent protection, and hiccup overcurrent protection. When secondary overcurrent protection is triggered, the built-in frequency reduction function decreases the switching frequency from 150KHz to 50KHz.
