Hi team,
I have a question about how TPS548B28 soft start work.
If use internal reference voltage, the constant current keep charging soft start capacitor Css until the voltage of SS/REFIN pin arrive internal reference voltage 0.6V. Generally, if constant current is still here, why Css wouldn't keep charging but keep voltage at 0.6V. I am curious about how TPS548B28 bypass the constant current when SS/REFIN pin charge to 0.6V and keep the voltage of SS/REFIN pin firmly.
BR,
Jimmy
