Hello
My Customer had start to design with TPS92518.
Customer think their calc. result of eq(5) in d/s p13 shows big error ( 8%) due to Vcstx and tOFF variation even though inductor L , Rsence had 0% error.
( I don't show the calculation process of result (8%) here, but I can show it if necessary in offline )
On the other hand, trimming using LEDx_PKTH_DAC for 100% of each device , is very hard for customer's production line.
Q1 distribution data
Anyway, can you provide distribution data for following in offline?
* Vcst (245mV(MIN)/255mV(TYP)/165mV(MAX) at LED_PKTH=255 at Ta=25 deg-C
* tOFF VLEDx=30V/ tOFFxDAC=255 3.2us(MIN)/4.1us(TYP)/4.8us(MAX) at Ta=25 deg-C
Q2 condition( confirm)
Is Variation of Vcst, tOFF variation includes all of lot to lot and also temparature(-40 to 150 deg-C) ?
Thank you for your support many times!
Best Regards
