Figure 25
Whenever MOS switch is switched on, a leading edge
spike
capacitances and the reverse recovery time of
secondary-side rectifier. This spike can cause the gate
drive to switch off unintentionally. In order to avoid a
premature termination of the switching pulse, this spike
is blanked.

The IC will enter into protection, turning off the gate
when voltage at pin 9 (PWM CS) exceed 1.0V for a
period set externally through pin 11 (PWM Pre-short).
The IC will be resetted when IC exit out of PWM BOP.

During External Synchronization, external clock is input
by the synchronization signal input. PFC output is kept
in synchronization with PWM output in 1:2 ratio. The
maximum allowable external sync pulse width off time
is 0.5µs.

The maximum duty cycle is selected based on the
above setting at the PFC Vsense and PWM SYNC
pins.
