L6562A overshoot suppression during start up

Question asked by raut.sagar on Oct 10, 2016
In my application used L6562A as PFC pre regulator. At initial startup observed overshoot at output,so mosfet gate is disabled. It is switched ON again once DC link capacitor discharged to it's regulated value.To discharge cap it takes 6~7sec  and i need turn on delay time <1sec.
Can you please share views how to eliminate this problem?
