Part Number: TPS92518
Hello
My customer had chosen TPS92518 ( MP will be soon) but
they had changed their shunt FET ( Rdson became 0.25 ohm smaller ) and flicker issue at 0.1% duty found...
Customer has optimized MAX_OFF from 70 to 90 and flicker…
Part Number: TPS92518 Other Parts Discussed in Thread: TPS92640 Hi all：
I have some problems with TPS92518：
1，The maximum current of TPS92518 is 5A, which should be 2.5a per channel, right?
2，Is the current value calculated by the following formula…

Hello
Thank you for your support.
My Customer is evaluating TPS92518 EVM, but did not have linear curve like as
TPS92518EVM users guide(Fig4).
I think this is not correct characteristics for TPS92518 EVM right?
Would…
Part Number: TPS92692-Q1 Other Parts Discussed in Thread: TPS92692 , TPS92518 , , TPS92682-Q1 Dear TI: There is a circuit requirement that we need to use the TPS92692 Boost to 36V 1A output,
and then use TPS92518 to Buck, output voltage 6 pcs of LED…
I understand that you are using multiple 518's on your test setup. Can you check that your SSNs are toggling as expected? See TPS92518 SLUSCR7 datasheet Section 6.5 "SPI Interface" and reference the various requirements for SSN setup and timing. You could…

Hello
My customer chosen TPS92518 and evaluating their ES board.
Anyway, customer has question about the switching frequency
which is set by TOFF .
So, we can calculate TOFF / Fsw from TPS92518GUI and calculation tool.…
Part Number: TPS92518 Dear Sir,
Thank you for your support.
I had discussed with my customer for the goal of 0.1% dimming with TPS92518.
I'm sorry but I have poor knowledge about shunt FET dimming.
Please allow me basic questions below.
I…
Dear Irwin-san
Thank you for your comment urgently!
Yes. this test is radiating testing at EMC site.
As per customer's test, to add cap across diode between BOOT and VCCx is effective, but
I will suggest to add subber C20 & R4 in Fig13 of TPS92518…
Part Number: TPS92518 Hello Sirs,
We use ShuntFET dimming try tps92518 EVM and find low current will have flick issue .
Find the first current cycle waveform will be different . Detail as attach file .
May I have your comment ? Is it reasonable…
