【应用】开关型BUCK芯片LM2576助力电流模块，外部电感使用标准规格，输出驱动能力达3A
在很多系统化和集成化的产品设计中，最常用的解决方案就是模块化设计，当然现在越来越多的厂家会外购成品模块，特别像电源模块，无线通信模块，接口模块等。在电流模块中BUCK的驱动能力也提出了更高的要求。
LM2576作为开关型BUCK芯片，提供了优异的线性和负载调整能力，内部含有频率补偿器和一个定频的52M振荡器，外部使用的电感为标准规格100μH。对于LM2576-ADJ来说设计中在输出引角和反馈引脚增加可调电阻可是实现电压的连续可调，输入电压全系列都可支持到40V，应用框图如下
综上，LM2576具有以下优势：
1，外部电感使用标准规格，设计更加方便成本更优；
2，芯片带热保护功能，防止芯片过热烧毁；
3，输出驱动能力达3A，满足小功率负载应用。
