Part Number: BQ76940 Good day, I had just finished soldering components into my board ( https://e2e.ti.com/support/power-management/f/196/t/771358 ), and would like to ask if there's anything I should take into account before actually powering up my board…
Hi Pratik,
The droop is implemented by summing a signal that is proportional to the inverse of the output current to the feedback reference (through R20 in image below.) This requires sensing the output current. If you are not already sensing the output…
Hello Arumugam,
I reviewed the power tip article and I understand the basic concept. The circuit as it is shown here, will work for duty cycles of 50% or less.
When the driver is on, DRV is driven close to VDD on the dot of the transformer, Q2 device…
Hello Gary,
Yes, I agree that the 100KHz entry in the table does not match with the curve. It is quite likely a typo. I do not see too much wrong in the PSRR plot you have generated. It is not atypical to see ~3-4B of variation in PSRR from device to…
Part Number: THVD1450 I need some help. In a specific application, the THVD1450's drive strength is too powerful, which leads to fast edges and higher emissions.
Could you help list what steps can be taken to reduce emissions?
I know you could use…
Part Number: BQ25570 Hello charger folks,
My customer is designing a solar related products, they have finished the BQ25570 schematic. please help to review the schematic then give your valuable comments. Thanks!
With the peak current half-bridge hard switching designed by 28069, when the three-phase power is greater than 320, the primary current of some main transformers will rise, as shown in the figure below. If you adjust the positions of the main transformer…
more tips to debug the SDIO issue in the native AM62/AM62P Linux document in case which was been ignored previously, especially

I have advanced a little bit. I have found this link : https://www.jeffgeerling.com/blog/2020/usb-20-ports-not-working-on-compute-module-4-check-your-overlays
So, with USB activated, my voltage is @ 4.995V on my USB ports and it doesn't go down.
Moreover…
