Voltage Loop
3.8.2
Due to the low frequency bandwidth of the voltage loop,
the dynamic response is slow and in the range of about
several 10ms. This may cause additional stress to the
bus capacitor and the switching transistor of the PFC in
the event of heavy load changes.
The IC provides therefore a “window detector” for the
feedback voltage V
VSENSE
at pin 6 (VSENSE).
Whenever V
VSENSE
exceeds the reference value (5V)
by +5%, it will act on the nonlinear gain block which in
turn affect the gate drive duty cycle directly. This
change in duty cycle is bypassing the slow changing
VCOMP voltage, thus results in a fast dynamic
response of V
OUT
.

Output Gate Driver
The output gate driver is a fast totem pole gate drive. It
has an in-built cross conduction currents protection and
a Zener diode Z1 (see Figure 15) to protect the external
transistor switch against undesirable over voltages.
The maximum voltage at pin 8 (GATE) is typically
clamped at 11.5V.

Gate Driver
The output is active HIGH and at VCC voltages below
the under voltage lockout threshold V
CCUVLO
, the gate
drive is internally pull low to maintain the off state.
