Part Number: UCC27211A-Q1

Tool/software:

I am comparing RevA and RevB of the UCC27211A-Q1 datasheet.

Q1: 5.4 Thermal Information has changed. Is this due to PCN# 20240723008.2?　(PCN adds AIZU along with DFAB)

　- If yes, how has it been affected?

　- If no, please tell me why it has changed.

Q2: The operating junction temperature for RevA is +150°C. For RevB, it is +140°C.

Is it possible to make it 150°C?

Hi,

The thermal information has indeed changed due to PCN# 20240723008.2. The revision history shows that the operating junction temperature was changed from 140C to 150C in RevB, so the device can safely operate at 150C.

Let me know if you have any further questions.

Thank you,

Vincent Liew

Hello Vincent Liew-san,

Thank you for your answer. Please tell me a little more.

- Is this change due to a change in PCN, that is, a change in Die?

- For 140°C, can I use the RevA datasheet?

Best regards.

Hi T.Torihata,

Yes, this change is due to the PCN.

Please use the RevB datasheet if the part is post-PCN.

Thank you,

Vincent Liew
