TPS92314: Vref distribution data

Part Number: TPS92314

Hello

Thank you for your support!


My customer chosen TPS92314 for 2019 LED Tube product.


/AC input 220 to 240V: not isolated

/LED Vf 60 to 85V

/LED If 350mA

/PFC necessary PF > 90%

/No dimming

He has following two-questions.

Would you please let me know following?

Q1 Vref=0.14V (MIN/MAX) distribution

I had your answer before as following ( 1.24V +/-4.8% ) >>>.

Thank you.

But customer still hope distribution data.

I think  mutual  accuracy of divider has " some" accuracy, but how is distribution  data  for 0.14V refference of TPS92314?

I had also found another post which discribes about internal reference 1.24V  distibution.... (1)

It seems 1.24V accuracy should be within +/-1.5% .

>"From my limited knowledge, the 0.14 V is resistor divided version of the reference voltage with 1.21 V as min, 1.24 V as typ and 1.3 V as max.

>In theory, it’s possible to have +/-5% LED current tolerance achieved."


Q2  Shipped to the Market

We know TPS92314 has RTM on 2012.

So, how many q'ty of TPS92134 had shipped to the market ?

( If you need biz size/ schedule info., I can inform you in offline)
