LM3429: Increasing the Max Input Voltage

Part Number: LM3429
Other Parts Discussed in Thread: TPS92075, TPS92074

Hello there,

I was thinking about adding a Zener diode/(Voltage regulator) to limit the VCC, and use appropriately rated components for the Buck-Boost configuration, so that I can use this IC for 8.5V to 120V DC input range.

Is it advisable?
