  Part Number: LMZ31506

  Hi

  Are the below three parts drop in replacement for one another

  I am designing a 12 to 5V converter

  Can I mount any of these for a common circuit

  TPS84621RUQT

  LMZ31506RUQT

  LMZ31506HRUQT

  Regards

  LMZ31506: About PWRGD terminal specifications of LMZ31506RUQR

  Part Number: LMZ31506

  Could you tell us about the PWRGD terminal specifications of the LMZ31506RUQR?

  There is a description of the TYP value for the PWRGD threshold, but there is no description of the Max value and Min value.

  Could you tell me about the value?

  LMZ31506： LMZ31506 Setting for 9V → 5V Step Down

  Part Number: LMZ31506

  LMZ31506 When setting 9V → 5V step down

  RSET 196 Ω
  It can be read from the datasheet that RRT 86.6 kΩ
  For COUT 1 and COUT 2
  How much should each capacitor capacity be set appropriately?

  LMZ31506: RoHS/REACH regulations

  Part Number: LMZ31506

  Hi Team,

  My customers know that the expiration date for RoHS / REACH exclusions is likely to be extended.

  However, the customer wants to remove it immediately, regardless of the regulation.

  I know that LMZ31506RUQR is a target.

  Do you have plan to change the following products to meet the RoHS/REACH regulations?

  If so, when are you planning?

  　LMZ31506RUQR/LMZ34002RKGR/LMZ31710RVQT/LMZ31503RUQR

  Bset Regards,

  Kenji

  LMZ31506: Layout of LMZ31506

  Part Number: LMZ31506

  Hi

  If I use LMZ31506 under design, what are there any problems?

  Should I connect AGND with PGND only 1 layer?

   1 layer：signal, LMZ31506

   2 layer：GND

   3 layer：Power

   4 layer：Power

   5 layer：GND

   6 layer：signal

  Best regards,

  Yokota

  RE: LMZ31506: About Power Good of LMZ31506

  The delay of the PGOOD signal is typically less than 1 ms.

  The delay is a function of the internal IC timing.

  RE: LMZ31506: Temperature de-rating curve

  Hello Jessica,

  The safe operating area curves (SOA), Fig 4, Fig 9, Fig 14, in the datasheet imply that there is no de-rating needed for the entire output current range. The maximum ambient in the application can be 85C. I think the y-axis should perhaps read "Maximum Ambient Temperature" instead of "Ambient Temperature". I believe this is where the confusion is coming from.

  Fig 15 shows the SOA for 5V out with 12V input. In that figure you can see a slight "knee" of de-rating at the max current.

  Let us know if this answers your question.

  Cheers,
  Denislav

  LMZ31506: Device SPICE odel pins 8 & 9 (INH/UVLO) does not seem to function properly as ENABLE pins

  Part Number: LMZ31506

  Hi team,

  customer is facing the following challenge. please advise.

  I’ve pulled the SPICE model for the LMZ31506 from TI’s website to do some simulations, and I noticed that pins 8 & 9 (INH/UVLO) don’t seem to function properly as “enable” pins. According to the datasheet, tying the two pins together should allow them to function as inhibit pins. I’ve done that and tried connecting those to ground, but my output is still enabling (see image). Is there a way that I can edit the .subckt to add in the “enable” functionality?

   

  thanks,

  Kevin
