Part Number: LM5176-Q1 Other Parts Discussed in Thread: LM5175-Q1 Hi, team
LM5176-Q1 only have CCM and hiccup mode, and customer want DCM mode to improve efficiency during light load.
Do you recommend switch to LM5175-Q1? or is there any strategy…
Hello Brigitte,
We are using both the regulators LM5175-Q1 and LM5176-Q2 for the output voltage of 12V and 5V, thats why there is two schematics.
1. we need to know whether we need to proceed with the components value based on Design calculator or…

Hi, Brigitte
Please check this post, it maybe more clear tor this problem.

Hi Greg,
Thanks for reaching out with your questions.
The difference between the LM5175 and the LM5175-Q1 is that the LM5175-Q1 has been qualified for automotive use.
The LM5175 can be configured to work in parallel using the method described…
Dear, Tim-san.
Thank you so much for all of your advice.
My customer is using LM5145 with external Sync(SYNCIN) = 425 ~ 500kHz, around 50% duty.
And LM5145's SYNCOUT is provided to following LM5175-Q1.
Now, they are checking the validness of…
Hi Bob,
1. The max value of the LM5145's SYNCOUT is approximately 4.5V (effectively a gate-source voltage threshold below the LM5145's internal 5V bias rail).
2. The duty cycle of the LM5145's SYNCOUT signal is 50%. This is ideal for synchronization…
Yes, you can consider the LM25117-Q1. You may also consider the LM5175-Q1, which is a 4 switch buck boost. Please create a separate post, either for LM25117-Q1 or LM5175-Q1, so the post can be responded accordingly. Please close this thread.

Hi Stefan,
We are currently trying out the compensation circuit you suggested. Attached is the WEBENCH report that served as the basis for our component values. (It took us a while to locate it.)
