to keep the VSENSE voltage same as the internal
reference 2.5V as shown in Figure 14.
Figure 14
The reduced bulk voltage can be designed by upper
side resistance of voltage divider from pin VSENSE.
Thus the low side resistance is designed by the voltage
divider ratio from the reference 2.5V to the rated bulk
voltage. A internal 300kΩ resistor will be paralleled with
external low side resistor of BOFO pin to provide the
adjustable hysteresis for PWM feedback voltage when
boost follower is activated.
The boost follower feature will be disabled internally
during PFC soft-start in order to prevent bulk voltage
oscillation due to the unstable PWM feedback voltage.
This feature can also be disabled externally by pulling
up pin BOFO higher than 0.5V continuously.

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 13 (GATE) is typically
clamped at 15V.
The output is active HIGH and at VCC voltages below
the under voltage lockout threshold V
drive is internally pull low to maintain the off state.
