Other Parts Discussed in Thread: TPS54229 你好,
我正在使用tps54229。看见这是Dcap2模式的,纹波很小。我想问一下,在设计的时候如何通过纹波和瞬态响应计算出输出电容的值。输出电容使用的是陶瓷的,ESR很小。我见过很多电流型芯片的计算方法。Dcap据说能实现更小纹波和瞬态响应,计算方法是不是也不一样?
谢谢!
Other Parts Discussed in Thread: TPS54229 , LM3224 , TPS54429 搞了一块TPS54229的板子还是四层的。做一下性能测试。电路板为TPS54229EEVM-056.
TPS54229是一颗DC/DC降压芯片,考虑的方案是7-18V宽电压输入,3.3V/0.8A输出,实际上TPS54229的输出能到2A。0.8A这样的带载能力相信能满足一般设备的需求。如下图:
实际应用中一般设备的功耗200—500mA电流就已经足够。WEBENCH设计的原理图如下左图…
