TLV62585: Reliability Qualification Report of TLV62585PDRL

Hi Lillian,

Please see the qualification summary for the device at https://www.ti.com/qualificationsummary/qualsumm/home?actionId=2800

TLV62585PDRLR-10005991.pdf

Let me know if this is something you were looking for.

Regarding your second question. We have efficiency data available for Vin 5V and Vout = 3.3V, 1.8V at page 12 in the datasheet. I need to check if we have available data for other output voltages. Meanwhile, Please let me know the following:

-- If there is any target efficiency requirement?

-- Target ripple specs requirement?

-- Load current for the ripple data? 

Thanks!

Best regards

Hi Sneha,

Thanks for your help!

Customer has no target efficiency requirement, now they do performance comparisons with competitors.

If you check that we have available data for other output voltages, please contact me. And selecting a step between idle and 3A to test load current is better.

Example shown as below:

Thanks!

Hi Lilian,

Thanks a lot for sharing project information.

I checked our database, we do not have measurement data available readily for other Vout values. I would have to do the measurement in an EVM. I need to check if I have the EVM available already. I can confirm this early next week. 

In order to conduct these measurements, please allow me sometime and I will keep you updated with the progress. Is there any preference on getting efficiency data or ripple data first? So that I could start with that measurement first. let me know.

Meanwhile, can you confirm if the measurement data for minmum Vout (0.8V)  and maximum Vout (3.6V) will be sufficient for the customer? In this way, we will know about the min and max values of efficiency. As for other Vout values, the efficiency values will lie in between the max and min value.

Let me know your comments.

Thanks!

Hi Sneha,

Really thanks for your help!

Customer need the measurement data for minmum Vout (0.8V) maximum Vout (3.6V) and 1.35V.

 if you get the EVM, please help test the efficiency firstly. 

Thanks 

Best regards

Hi Lilian,

Okay. Got it. 

I will update you by early next week.

Thanks!

Hi Lilian,

Meanwhile, Do you know who is the competitor here? 

Best regards

Sneha 

Hi Sneha,

The competitor information is confidential from customer side now, but I heard competitor has provided the data what they want. I try to get more info, if any update, I will contact you.

Thanks 

Best regards 

Lillian

Hi Lilian,

Okay. Thanks.

Hi Sneha,

I heard from my customer side that our competitor has provided their efficiency data, so my customer is urgent for our efficiency data to do comparison, could you help provide these efficiency data in this week? 

In addition, what they concern most is the efficiency of light load.

Thanks

Best regards

Lillian 

Hi Lilian,

Okay. I will update you by end of the week.

Hi Lilian,

Please find below the efficiency measurement results for TLV62585 with Vout = 0.8V, 1.35V and 3.6V and Vin = 5V.

Let me know in case you have questions/comments on this.

Thanks!

Hi Sneha,

Thanks for your help!!

Hi Lilian, 

In order to proceed the ripple evaluation, please provide the load current values at which the customer would like to evaluate the output ripple. Generally speaking, higher output ripple is observed at PFM mode as compared to PWM mode. 

Thanks!

Best regards

Sneha

Hi Sneha,

My customer need ripple data of load current value:0mA, 50ma,100ma,150ma,500ma,1A,3A.

Thanks 

Best regards

Hi Lilian,

Okay. I will provide you the measurement results by early next week.

Thanks!

Sneha 

Hi Lillian,

I have shared the ripple measurement data by email.

Thanks!
