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 duty cycle adjustment range of 0~100%. It integrates an onboard fixed-frequency oscillator and frequency compensation module, minimizing the required external component count. Additional integrated features include hysteresis-enabled enable control, over-temperature protection, overcurrent protection, and secondary overcurrent protection. When secondary overcurrent protection is triggered, the built-in frequency fold-back function reduces the operating frequency from 150kHz to 50kHz.
