Hi Given,
I believe the connection between the OSC with PLL and the VSENSE pin may have been a re-use mistake. I bet this block diagram came from another part which had frequency foldback. In these parts the Vsense voltage will influence the fsw so…
Part Number: AM6548 Other Parts Discussed in Thread: TPS54618 , TPS62827 , Hi all,
During the HW verification process of our board with the X6580AACD device, we have noticed a strange behavior of BOOTMODE and MCU_BOOTMODE pins. The screen snapshot…
Part Number: TPS54388C-Q1 We are using TPS54388C generate UG1V form UG5V. Relevant schematic as attachment.
I have measured TPS54388C output voltage vibration during SCH UG1V.pdf rise time.
Do you have some ideas about this issue?
SCH is attach…
There will be some delay between rising edge of EN and the start of switching. It should be ok to have CLK present with EN. Are you using the same signal to enable the TPS54618 and enable the CLK buffer?
Hello Piotr,

Did you have a look at the TPS62816-Q1 as…
Part Number: TPS54521 Tool/software: Hi TI Team,
We are planning to incorporate the TPS54521 in our design to convert 12V to a stable 1.8V output at 2.5A. I have attached the schematic and calculation sheet for your reference.
Could you kindly review…
Thank you for sending the waveforms.
The 19kHz signal that they measured indicates instability. This is probably causing the PG signal to trip. Have they measured the stability of this design or measured a bode plot?
Can you also confirm that R33…
Other Parts Discussed in Thread: TPS54618 Hello team,
I would like to know if there's possibility to have trouble (some output voltage over/under shoot) when apply and mainly remove external synchro please ?
I remember bad experience with TPS54618…
