Part Number: LMZ12002
Tool/software:
Hello, Can you please review the design of LMZ12002TZ-ADJ/NOPB. I have designed 2 circuits, one is for 3.3V(U103) output and other is for 5V (U101) output using same IC.
I have attached a PDF files of the same…

Hello,
About the enable pin of the DC-DC lMZ12002, in the "absolute maximum ratings" part the maximum voltage allowed is V_(EN MAX) = 7V but in another part of the datasheet it is described that is possible to leave pin enable…
Ibrahim, it appears you have asked this same question in this thread: https://e2e.ti.com/support/power-management/f/196/t/921609
Let us continue and close it there.
Part Number: LMZ12002 Hi, Good day. Our customer would like to know the peak body temp of TI make LMZ12002TZ-ADJ/NOPB. Is it the same as the max storage temp? which is 150C? Thank you. Regards, Cedrick
Hi Michael,
Thank you for the information. If you have any further questions please let me know. Also if this issue does happen again feel free to reply to this message so we can reopen this thread and continue troubleshooting. Customer returns help…
Part Number: LMZ12002EXT Other Parts Discussed in Thread: LMZ12002 , Tool/software: WEBENCH® Design Tools The WEBENCH Designer does runs and supports 4.5V-5.0V input for 3.3V and 1.7A output on the LMZ12002 but not the LMZ12002EXT; however, at higher…

Hello, i want to get from LMZ12002 VOUT=6-7v IOUT>1.5A with VIN=11v and i have problem. I have only 4.5 VOUT ... I can't get VOUT>4.5V, my schematics is attached. I think this is my mistake and LMZ 12002 needs more drop voltage…
Sorry, i just realized that your input is lower than your output.
So yes, the mosfet will be on at maximum duty cycle try to meet the 5V but at the end it will not be able to get to 5V
So at 4.5V input, the output most likely will drop to be lower than…
Hi Anston,
I am SO sorry for the late reply!! The email notifications were going to my junk so I had no idea you had responded! I should have just checked the site.
But yes, you were correct. My wall adapter was not performing as I expected it to…
Other Parts Discussed in Thread: LMZ12002 We have make 3 boards with LMZ12002.
According to the datasheet, we set the output to 5V using two resistors. We have double checked the value, but the output voltage is only 3.7V.
The feedback voltage is…
