Does anyone know whether this converter is voltage mode or current mode converter? I think this IC is a voltage mode converter as the compensation ramp circuits cannot be seen from the datasheet, am I correct?
If it is a voltage mode, why the transient response performance is so good as typically, voltage mode converter has slow transient response/small bandwidth? Thanks a lot.

Hi dennis,

yes you are right, it is a voltage mode converter. I think the transient response is reasonable as the UGF is around 100kHz as stated in the datasheet.
