Introduction

AI Translation

The LM2575 is a 50KHz fixed-frequency PWM DC-DC switching regulator capable of delivering 2A output current, featuring high efficiency, low ripple, and excellent line and load regulation. The device operates in PWM modulation mode with a linearly adjustable duty cycle ranging from 0 to 100%. It integrates a fixed-frequency oscillator and frequency compensation module, requiring minimal external components for ease of use. Additionally, the chip incorporates enable control 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.
