UCC24612: UCC24612 VDD power supply

Hi team,

I have a question about the UCC24612 VDD power supply. In our datasheet picture, the VDD is powered from Vout through a Diode and resistor. But in our EVM schematic, a zener diode D1 is required. I thought the picture in our datasheet is a simplified picture and the zener diode is a must here. Can you help confirm? Thanks.

Best regards,

Wayne
