您好，推荐一款4.5-5.5V升12V的芯片，输出电流能力大于等于1.5A，电路最好简单，内置mos。
要求车规级
Hi
在升压芯片list下设置条件： https://www.ti.com.cn/zh-cn/power-management/non-isolated-dc-dc-switching-regulators/step-up-boost/boost-converters-integrated-switch/products.html#p238min=0.3;4.5&p238max=5.5;75&p634min=-70;12&p634max=12;84&p834typ=4.6;16&p212max=62.5;100
适合的芯片很多，选择开关保护电流大于5A以上，例如：TPS55340-Q1,LM5157-Q1
(可以再用webench设计确认一下，也可以直接用webench选型，更方便更准确）
