TI中文支持网TI有没有这种DC/DC，当输入电压为5V或12V时，输出电压都为稳定的5V，输出电流2A~3A。
answer：
可以考虑TPS40210

Hi电源转换一般输入都是可以有范围的，也就是说，你找的芯片输入范围至少是5~12V,输出5V/3A可以用升降压芯片，例如LM25118

The PMP30331 reference design is for an input voltage from 5V to 16V.Cranking is possible for voltages as low as 4V and load dump for voltages to 36V.This reference design uses the SEPIC topology as a cost effective alternative for 4 switch buck-boost (for low power).
