S12ZVM boost converter

Please check whether my understanding is correct about S12ZVM boost converter.


There are the specs about boost converter in S12ZVM as below,

VSUP boost turn on trip point V_BSTON : min 9.5V, typ 10.1V, max 10.6V

VSUP boost turn off trip point V_BSTOFF : min 9.75V, typ 10.3V, max 10.8V

My understanding is that:


1. These means

- when the VSUP becomes below V_BSTON, then the boost converter operates


- when the VSUP becomes above V_BSTOFF, then the boost converter doesn't operate.


2. Therefore, there is the hysteresis features and the boosted VSUP voltage has a ripple equivalent to V_BSTON-V_BSTOFF during boosting.



Is my understanding correct?
