7.9 Protection overview
Capacitive mode is detected when the HB slope does not start within t
MOSFETs have switched off. Detection of Capacitive mode will increase the switching
frequency. This is realized by discharging the soft start capacitor with a relatively high
current I
started. The frequency increase regulates the HBC to the border between capacitive and
inductive mode.
