Tool/software:
Hello guys,
One of my customers is evaluating TPS92641 for their next products.
At this moment, they have the following questions.
Could you give me your reply for them?
Q1.
Is TPS92641 error amp (EA) output switch behavior same between UDIM H/L control case and SDIM H/L control?
I think it is different and a switch which connected to EA output would be close/open depend on UDIM H/L level (SDIM=H).
Also I think the switch would be always close regardless of SDIM H/L level (UDIM=H). And the switching on time becomes the minimum when SDIM=H.
Is my understanding correct?
Q2.
COMP pin is always charged to a voltage when SDIM=H (LED off).
Could you please explain about internal circuit behavior?
Q3.
We confirmed rising speed of LED current is changed depend on comp charged voltage at just before SDIM turning L.
Is there any countermeasure to reduce this LED current rising speed variance
Your reply would be much appreciated.
Best regards,
Kazuya.
