我看TPS6103*的手册，标题写可以开关4A（TPS6103x 96% Efficient Synchronous Boost Converter With 4A Switch），
但后面说5V时输出电流时1A（It provides high efficient power conversion and is capable of delivering output currents up to 1 A at 5 V at a supply voltage down to 1.8 V.）
这芯片到底是输出1A…

Other Parts Discussed in Thread: CSD17556Q5B 请教： pcb完全按照附件电路设计，因为手上有CSD17556Q5B所以NMOS换成了这个，肖特基二极管换成了国产厂家的 MBR10200，我对比参数很接近。 我用4欧姆水泥电阻负载测试时，输出电压电流都正常，NMOS管发热也不大，但二极管发热很厉害，能看到有烟出现，但是多次测试好像元件并没有损坏，输出都正常。 请问下是我电路有问题，还是应该给二极管加散热片？ 谢谢！
