I'm planning to use the LDO for our basic power stage circuit (without MCU).
In the datasheet, we find the Reset pin, Watchdog pins should be connected with MCU.
In our case, we don't use these reset & watchdog pins.
I couldn't find the information about the unused pins in the datasheet.
Should I leave these pins Open or Pull up or Pull down ??
Kindly help me with this.
Thank you
Show LessDear Infineon experts:
Currently we have known that we could do TLF35584 boost converter loop stability analysis based on the online simulation tools from Infineon website.Some customers want to test the loop on the board.So can you advise how to implement the test setup for stability analysis ( for example how to select the injection point?)based on the typical TLF35584 BOOST/buck circuit environment ?

Dear Sir,
I saw this 30W refernece design. can ICE5QR1680BG EVM work in input DC100V~400V? thanks.
Show LessDear all,
We are using TDA21490 with a PWM multiphase controller in an application delivery up to 600A to a processor.
Due to some external constraints, it may happen that we have transient on the generated PSU. As such, we are seing -1V or >5v for a few 10ns on the VOS pin which exceed absolute maximum rating
We suspect this is the cause of some latch up damaging a few devices/boards. We are working on getting rid of those transients, but we would like to prevent them of damaging the part a are thinking adding Schottky bridge with 50 ohm in serial with VOS (See attached schematic).
My understanding is that VOS is used somehow for the current measurement.
Is the 50 ohm going to prevent from measuring properly the current? Is it going to prevent the TDA21490 from working properly ?
Thanks for any clarification and recommendation you can bring.

Show LessDoes any brother know how CHL8325B reads and writes the program in the chip?
Hi Infineon,
I am working on TLF35584 PMIC IC.i am able to transit from INIT to Normal state when WWDG ,FWDG,ERROR PIN monitor function disabled while MPS pin is HIGH.
But when i enable the Error pin monitor and disable both watchdogs while MPS pin high as above condition .try transit to normal state ,TLF remains in init state itself ,could anyone tell me what is the reason behind this behavior.
Thanks,
Krishnayya
Show LessIn the datasheet it is mentioned that the chip has a fully programmable ARM M0 controller. I am looking for a multiphase PMIC with programable feature for my project. Is there any software development kit/documents available for this product?
