TPS65150: the range of cutoff frequency of the feedforward zero formed by R1 and CFF

Fandy

Part Number: TPS65150

Hello

Vin=3.3V, Table2 recommend fco=7.8KHz,my customer select below parameter, so if it is suitable ? how much the range of fco?

R1：130kΩ(±0.1%)

CFF：150pF(±5%)

Fco：8.16kHz(typ)、7.42kHz(min)^8.22kHz(min)

Hi Fandy,

Your circuit is approx. +/-5% tolerance from 7.8KHz and it is ok to use these values in this circuit.

Kind Regards,

Liaqat
