Part Number: LM3478 I have designed a boost DC-DC convertor circuit using LM3478. The input voltage is 12V,13A (via AC-DC Power Supply) and the output voltage 24V,5A. Circuit has been worked fine for few days and suddenly the convertor is not working…
Part Number: LM3478 Other Parts Discussed in Thread: LM5022 , , POWERSTAGE-DESIGNER I asked Webbench for a SEPIC converter using the LM5022 or LM3478 20V-60V input 48V @ 1A output, and it says it can't, but it doesn't say WHY it can't.
I have not seen an update from you for the last 25 days, so I assume the questions are answered and the issue is solved. I close this thread now. If there is still something open, please reply and the thread will get opened again. If you have…

There are few points I couldn't understand about current sense functionality in LM3478.
The option to set current limit by choosing Rsn works like if voltage across Rsn (which is…
Part Number: LM3478 Hello,
I want to use LM3478 as a simple led driver, schematic is attached. The problem is that I can't get a stable duty cycle on the DR output. Components mostly follow the WEBENCH POWER DESIGNER. What went wrong?
Part Number: LM3478 hi teams:
The customer has a product that uses TI's LM3478, with an input of 4-17V and an output of 5V/0.3A.
Currently, there is a problem that when the input power fluctuates at low frequencies, the inductor L2 will make a noise…

I am using LM3478MMX/NOPB for a boost topology and the device works fine at room temperature. When transitioning to cold (~-25C) the regulator no longer boosts the output to the 200V output that I need.

Part Number: LM3478 Other Parts Discussed in Thread: PMP20183 Hi Team,
We would like to ask your help regarding our customer's inquiry below.
I'm writing this email to ask you my doubts about my design.
My design is an SMPS boos converter, with…
I have not heard from you for more than two weeks now, so I assume you have found a solution. I am closing this thread now. Please open a new one in case of additional questions.
