Part Number: LMQ644A2-Q1 Tool/software: Hi team,
Could you please advise the tolerance of fb pin at 3.3V and 5V fixed?
It is described as below in the top page of the datasheet, but Vfb1/2, Vfb_so is specified as min/max 1.5% in EE table for adjustable…
Part Number: LMQ644A2-Q1 Tool/software: Team,
We use the LMQ644A2QRXARQ1 part number for 3.3V and 5V conversion for 24V. But we are facing continuous issues in that IC. I don't know why this happened, but I used the TI web bench for reference. I will…
Part Number: LMQ644A2-Q1 Tool/software: Dear Sirs,
we use the above device in a dual output mode (config pin 121k to GND) and we dont want to use PG1- and PG2-Pin. Datasheet states that both pins are open drain and need an external pull up.
If we don…
Part Number: LMQ644A2-Q1 Tool/software: Hello everyone,
I am currently working on a design using the LMQ644A2-Q1 regulator for generating 2.5V@12A in stackable/single ouput configuration , and 1.8V@6A, 1.5V@6A in dual output configuration and would like…
Part Number: LMQ644A2-Q1 Tool/software: Hi team,
Is it possible to configure this device as single phase 3 or 5 phase (odd number of phases) ?
If the answer is yes and can be used for 5 phases(use 3units of LMQ644A2), do I need to populate LC components…
Part Number: LMQ644A2-Q1 Tool/software: hi Team,
So, on this link I find empirical data, reporting (see image attached below) a figure of 0.1 FIT for the LMQ644A2QRXARQ1 part.
However, on this link I find, for SN 29500-2 a figure of 25 FIT.
Which one…

Tool/software:
Hi team,
In D.S, it is described that low side current limit is 5A. Is this for each channel? i.e. can this device flow 10A for sum of two channels?
Best regards, Goto
Part Number: LMQ644A2-Q1 Tool/software: Dear Sirs,
I have a question regarding sync pin of LMQ. We use the device in dual output mode. The question arrises, what to do with the sync pin. Is it allowed to let it float, to let the LMQ decide what PWM mode…
Part Number: LMQ644A2-Q1 Tool/software: hi expert,
my customer use two LMQ644A2, VIN =12V Vin max =36V , Vout=3.3V Iout max= 20A.
but when they test the total output current just up to 5A, the output voltage is 0V.
could you help review the schematic…
Part Number: LMQ644A2-Q1 Tool/software: Dear Sirs,
I have a question regarding sync pin of LMQ644A2-Q1. When device configured for single output dual phase and pull up to 12A,How to achieve the average current of each phase?Will there be a phenomenon…
