Hi @all,
I'm using the TPS59610 IMVP buck controller.
The Datasheet SLUSA34 (March 2010) recommends a capacitor of 1000pF (page 7) between VREF and GND.
On page 10 there are 220nF used.
And within the users guide (sluu465 page 7) a capacitor of 1µF is used.
Is a 1µ necessary to provide stable operation?
With 1nF the voltage isn't stable and the controller is running into a reset state.
With 100nF or 2x100nF or 220nF or 1µF the voltage seems to be stable.
Which value do I need at least to be sure to buffer the voltage well?
Kind Regards,
Thomas
