Introduction

AI Translation

LM2576 is a high-efficiency step-down DC-DC converter with a fixed 52KHz switching frequency, capable of delivering up to 3A output current. The device features low ripple, excellent line regulation, and load regulation. An integrated fixed-frequency oscillator and frequency compensation circuit simplify external circuit design. The PWM control loop enables linear duty cycle adjustment from 0% to 100%. The device also incorporates an enable function, output overcurrent protection, and thermal shutdown protection. The internal compensation module helps minimize the number of required external components.
