Introduction

AI Translation

The LM2576S series is a family of easy-to-use, fixed and adjustable step-down (Buck) switching mode voltage regulators. These devices are available in fixed output voltage versions (3.3V, 5V, 12V) and an adjustable output version. Both versions are capable of driving a 3A load current with excellent line and load regulation. These regulators require a minimum number of external components, are easy to use, and include internal frequency compensation and a fixed-frequency oscillator. Output voltage is guaranteed to within ±3% tolerance under specified input voltage and output load conditions. The oscillator frequency is guaranteed to within ±15%. An external shutdown function is included, with a typical standby current of 80 µA. Self-protection features include a two-stage frequency-reducing current limit for the output switch and a thermal shutdown function, providing comprehensive protection under fault conditions.
