UCC28083: Webench maximum input voltage

Part Number: UCC28083

Hello Guys,

Good day.

Our customer wants clarification on the maximum input voltage of UCC28083 on Webench. Why does Webench limit Vin to 70V?  When a separate Vcc of 12V is used, the only electrical limit on Vin is the voltage rating of the push pull transistors.

Thanks in advance!

    Thanks for your interest in TI here. Let me assign to an applications engineer to this post to comment further.

  • Hi,

    The IC is ok to work with VDD in the range but the webench adds its own capability for a design input range. So you cannot use the webench for Vin > 70V. You need to design on datasheet. We will inform the webench model team to ask to extend the Vin range but such a request cannot be done right away. A typical cycle is a few months depending on the team work load and back order/request.
