PRODUCTION DATA
The buck converter is limiting its switching frequency when its output voltage VCC is below a certain threshold (fSWB = 1/4 × fosc for VFB_internal < 400mV and fSWB = ? × fosc for VFB_internal < 800mV). This feature avoids run away of the inductor current in case of short circuit and helps smoothing the buck converter startup as well.
