Issue Summary – LM5176-Q1 Buck-Boost Humming Near VIN ≈ VOUT
We are using LM5176-Q1 in a 4-switch buck-boost design, generating 28 V output from a 10–30 V input range.,Vout is set for 28V.
V1.0 board…
Part Number: LM5176 Other Parts Discussed in Thread: LM51770 , LM51772 If the LM5176's FB pin fails and is pulled to GND, it will likely continue to boost the output voltage. I would like to confirm the output voltage at that time.
Input: 12V Output…
Part Number: LM5176 Tool/software: Hi,
We use the LM5176 in the buck circuit, the input voltage is 24V, and output voltage is 12V;
Now, the temperature of the MOSFET will rise above 80℃ when the output current more than 5A;
Plesae refer to our schematic…
Part Number: LM5176 Other Parts Discussed in Thread: LM51770 , LM51772 Tool/software: Hi TI ,
I check datasheet MODE pin only CCM for hiccup enable/disable.
Could I setting DCM mode on LM5176 ?
Part Number: LM5176 Tool/software: I've entered the exact application schematic from the LM5176 datasheet into TI PSpice. I've tried and tried to get it to simulate, but I can't seem to get around convergence errors to complete the simulation. It runs…

Hi Support Team,
We are working on a project using the LM5176 in Buck-Boost configuration , with the following operating conditions: VIN = 9–48V, VOUT = 20V, IOUT_MAX = 12A .
During development, not all functions…
Hi Hyunkyu,
We apologize for the delay in response. In regards to the issue reported with respect to LM5176 as per the suggestion from product expert we have extended the maximum output current supported by device to 40A and we have added the maximum…
Part Number: LM5176 Tool/software: LM5176's datasheet says that Vin's operating current is 2mA typ, 4mA max. (And based on the block diagram, I would think that whether it's Vin-only or Vin+Vbias, the total current into the chip would be nearly the same…
Part Number: LM5176 Tool/software: I have designed a dc-dc converter using the LM5176. However, when I connect it to power, it is only able to work if I touch my finger to the capacitor on the comp pin. I am assuming that this is due to the extra capacitance…
