Because of the Thanksgiving holiday in the U.S., TI E2E™ design support forum responses may be delayed from November 25 through December 2. Thank you for your patience.
Hi Asael,
Is the waveform captured with Vin=13.5V, and load=2A? And input voltage keeps supplying but you observed Vin on and off Intermittently? Please check if the current limit of the input supply is set too low to provide enough energy.
And from the…
Hi Franz,
Please have the customer send over the schematic and a filled out version of the quick start calculator tool to help me get an understanding of their application condition and requirements.
It also wasn't clear to me if the customer concern…

Hi Farzaneh,
Thank you for the schematic. It seems like you are controlling the fan by raising the VOUT of the converter dynamically using a PWM waveform.
For this solution I recommend…
Part Number: LM25085 Other Parts Discussed in Thread: LMR36015-Q1 Hi,
i'm looking into potential replacements of LM25085 which not necessarily have to be pin-to-pin as we're working closely with customer on a tight BOM cost project. Here are some of…
Part Number: LM25085
Hello
A customer said if the LM25085 output current exceeded 5A, the output voltage will drop. i will get more detailed information to you, but I have a question about its maximum output current if it's depended on the MOSFET Q1…
Part Number: LM25085A Other Parts Discussed in Thread: TPS53318 , LM25085 Dear support member
My customer used LM25085A.
I have two question.
Q1. Even in the configurations of Fig 28, Fig 33, and Fig 34 in the data sheet Is the equation for calculating…
Hi,
From the schematic, R4, C7 and C8 need to be populated if you don't have enough ripple at the output .
I also tried to put in your design parameter into the calculator and it gives me warning that design over 8A is not recommended.
I attached…

Hi Tadeusz,
That link works fine on my browser. I attached the quickstart calculator file.
I suspect the inductor is the root cause of the issue - maybe you can test with an inductor that is adeqautely rated.
