LM2576T-12

LM2576T-12是一款单片集成开关稳压电源，属于降压型稳压器。它具有输入电压范围为12-45V，输出为-12V，最大输出电流约为0.7A。该电路采用了自举电路，将稳压器的原地变成负电压的输出端，从而实现负电压输出。为了实现Buck变换，推荐的电感量范围是68~220uH，输出电容必须大于降压式变换的要求。对于低输入电压或大输出电流，输出电容应不小于1000uF。在需要的情况下，还应给LM2576T-12安装散热器以提高散热效果。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
