We are developing a battery charger 24V lead.
We design with the WEBENCH but does not deliver current.
We replaced Cff by 1uF and delivers 100mA.
which may be the cause?

Hi Ruben,

Please provide more detail on what kind of behavior you are observing in the circuit? Perhaps some waveforms of SW and IL (inductor current) will be useful.

Thanks and regards,
