最近在看几间大厂的新型技术发现TI D-CAP D-CAP2 还是 RICHTEK ACOT

产品好像都是Buck (constant on time) 而相对Boost 采用 COT(constant off time)却很少见

想请叫大神这其中的原因

peak current_constant off time boost，constant on time_valley current mode。也是有的。和COT对应的boost ripple regulator也有的。

I think that output current of boost is discontinuous, which makes it difficult to sense
output ripple like COT buck
