LM2576 is a buck switch regulator with small voltage adjustment rate and current adjustment rate, capable of outputting multiple fixed and adjustable voltages. It is suitable for applications such as high-efficiency buck regulators and positive/negative voltage converters.
The document describes the LM2576 as a step-down switching regulator featuring low quiescent current and high efficiency. It supports both fixed output voltages (3.3V, 5V, 12V, 15V) and an adjustable configuration ranging from 1.23V to 30V. This manual is written in Chinese.
