Page 14 of the LM3421 datasheet says that constant off time boost converters have a "right half plane zero".
Surely this is not so?
The RHPZ effect, is where the off-time gets progressively minimised when there is a sudden need for more power throughput....however, in a constant off-time converter, the off-time is fixed, and so cannot get minimised....so how can there be a RHPZ?
