MPQ3362 and FB pin protection

DC-DC Power Converters
1

Hi, I want to use the MPQ3362 for switching leds (13 volt) at around 3 amps. In the datasheet, it is suggested to protect the FB pin with aither a diode and or a series resistor and a zener. Any suggestions for the values / types?

thanks in advance.

Hi Robbie,

Please size the diode/zener such that the voltage on the FB pin does not exceed +5.3V during the short load condition.
