TPS65185 / Absolute Maximum Rating of VDDH_D.

ACGUY

Other Parts Discussed in Thread: TPS65185

Hi all,
I work at Japanese distributor.
Please let me know about VDDH_D's maximum output voltage of TPS65185.

VDDH_D voltage is written, 22V ± 2V to the data sheet.
This device can adjust VDDH_D by VDDH_FB with resisters.
VDDH_DIS absolute maximum voltage is 30V.
Our customers will 27V the VDDH_D.
However, VDDH_D's absolute maximum rating isn't written in datasheet.

Do you know the maximum voltage?

Best regard,

You can technically do this by adjusting the resisters. However, I would be aware of ripple causing the output to go above 30V and this could add extra stress to the device. Since this is out of spec we have no test data on the stress by going above 22V.
