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% .

>This is the information I received:
>"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)
