With the information from the previous posts that the LMZ14201 sources 6uA out the EN pin, limited at 6.5V. And knowing the turn-on threshold of the LMZ14201 is 1.25V max then a resistor to ground of at least 1.25V/6uA = 208Kohm is the minimum to turn…
We will provide you TINA-TI encrypted model of LM3880 as soon as possible.
We are not committing for any date as of now and get back to you once it get completed.
Thanks,
Vivek Agarwal
Other Parts Discussed in Thread: TINA-TI , TPS56339 , TPS2420 , LM3880 Tool/software: TINA-TI or Spice Models Hi,
Can anyone share with me a TINA-TI circuit that has LM3880, TPS56339, and TPS2420 components?
P.S. I already tried to look for these…
Other Parts Discussed in Thread: LM3880 I am using LM3880-1-AA IC to control power on and power off sequence for a xilinx FPGA.
I am controlling three DC-DC converter enable pins with the sequencer IC LM3880.
But as per the previous revision of the…
Part Number: LM3880-Q1 Hello,
Could you please let me know the recommended pad layout of LM3880-Q1?
I got the bxl file and install the ultra librarian. Then open the file, there is no actual size information (mm, inch or etc..) I appreciate it if…
Hello,
I am curious to know what Vcc voltage you are using and what regulators you are using? And when you say "they seem to drop a bit below desired value" are you talking about the input rail voltage or the output voltage of the regulators? Lastly…
Other Parts Discussed in Thread: LMZ31506 , LM3880 Hi
My customer will use LMZ31506 and LM3880 under Vin=12V and control enable of LMZ31506(INH terminal) by LM3880.
As long as I watched 4page of attached document, I think the voltage level of…
Why is it good to leave EN open? It is supposed to connect instead of floating.
If you tie the EN to a ground or 3.3V to see whether the Flag will be low or high with 100K pull-up when VCC is normal.
1) Does LM3880 is very sensitive chip ( ESD or…
Michael,
thank you for your response. Sorry, what I meant by EN1,2,3 were actually FLAG1,2,3.
The problem seems to be fixed by placing a 0.1uF decoupling cap close to the LM3880. I haven't confirmed it yet, but I suspect a glitch on the input supply…
