Hi,

Could you tell me about V(CSP-CSN) Threshold vs VCSP spec?
Customer wants to know V(CSP-CSN) Threshold vs VCSP in the case of VIADJ = 0.14V.

Do you have that graph data?
Or do you know the trend in that case?

Best Regards,

Yusuke

Hi Yusuke,

We only characterize that parameter for VIADJ of 2.1V. We do not have data for this at 0.14V.

Thanks Tuan

Tuan-san,

Thank you for you response and support.
I understand your comment "only characterize that parameter for VIADJ of 2.1V"

May I ask one more question?
Please tell me the change trend of graph when changing from 2.1 V to 0.14 V.
When lowering the VIDJ voltage, please tell me the graph trend.

Best Regards,
Yusuke

Yusuke-san,

Since we do not characterize or test that at 0.14V we do not have that information or know the trend that you are asking for.

Thanks Tuan

Tuan-san,

Thank you very much for your confirmation.
Customer want to dimming in reduce the LED current.
Therefore, Customer want that information.

Please let me ask one more question.
Do you have VCS (offset) variation data in VIADJ = 0.14V ?

Best Regards,
Yusuke

Thank you very much for your confirmation.

Yusuke-san,

We do not have the data at a particular input voltage of VIADJ of 0.14V. In general, if it's not in the data sheet then we do not collect data for it.

Thanks Tuan
