Part Number: LM5176 Hi,
We use the LM5176 for the DC/DC buck circuit, and now, there are more than 7 boards LM5176 maybe damage because we change the damage device to new one, the output voltage is nomarl;
Please kindly review the below schamatic and the…
Part Number: LM5176-Q1 Hello,
I have designed this for 9V -36V, 11 A load current. My design does not work at the minimum input voltage 9V-10V at full load.
It only works at higher voltage input from 20V -36V.
I tried adjusting RT, Vslope, no success. …
Hi,
fortunately, I have seen that there was a Mail sent by you. As mentioned please also make a note here that a private message has been sent.
For the layout:
Connect Current Sense resistor with Kelvin Connection
Make a AGND island for the LM5176 (AGND…
Part Number: LM5176 Hi TI Team, We are facing some out issue in LM5176 boost mode configuration. We used LM5176 calculators sheet and designed the same. Our Input Voltage range 24 to 33 Nominal Input voltage 28V Output Voltage 30+/-0.5V After designing this…
Part Number: LM5176 Hi TI team,
We are preparing use LM5176 in our new project. The operating condition is VIN=9-48V / VOUT=20V/IOUT=12A (max).
And we got a design file to simulation LM5176 system, we found that when VIN=9V and IOUT around 11A the efficiency…
Hi Brigitte,
Power on delay time for LM5176 provided by TI simulation is from 97us to 560us( https://e2e.ti.com/support/power-management-group/power-management/f/power-management-forum/1311119/lm5176-q1-lm5716-power-on-delay-time) , this parameter seems…
Hi Stefan,
We removed ADC input resistor R10131, there is no change. According to tested waves, this rise higher and drop phenomenon are related with working modes transfer, as mentioned above, when input voltage increase to 14.5V, LM5176 will always…
Part Number: LM5176 Hi Brigitte & TI Team,
We are facing an LM5176 IC damaging issue while testing above 5A load with input voltage 33V & 30V output voltage. Issue Details are as below: We used the same values as mentioned in the LM5176 evaluation…
Part Number: LM5176 Other Parts Discussed in Thread: CSD18532Q5B Hi,
Would you please help review below 12V buck-boost VR?
PQ21 & PQ22 will be replaced with CSD18532Q5B (60V), please kindly review the design and get back to us, thank you.
