SSL4120T
Resonant power supply control IC with PFC
Capacitive mode is detected when the HB slope does not start within t
to(cmr)
after the
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
cmr(hf)(SSHBC)
from the instant t
to(cmr)
has expired until the half-bridge slope has
started. The frequency increase regulates the HBC to the border between capacitive and
inductive mode.
