Hi Garrett-san,
Thank you for your quick response.
I just modified the excel calculator, so please confirm it just in case. Additionally, if these coefficients are applied to the LM51551, which doesn't work normally, the competitor products will be used…
Thanks for your answer,
LM5155EVM-BST is on the way, but I have some analysis to do before it's here.
About the FET's parasitics. Does the WEBENCH evaluates all the dynamic characteristics from FET's datasheet (capacitances, charges and etc.)? Or…
Hi Chanoh,
Thanks for reaching out with your questions and for considering the LM3481 and LM3478.
I am curious at why you think the LM3478 would not work of the application? At light load the LM3481 and the LM3478 are both going to have pulse skipping…
Part Number: LM5155 Other Parts Discussed in Thread: , LM5122 , TPS40210 Tool/software: WEBENCH® Design Tools Hi,
I plan to use the lm5155 for one of our product that needs to meet the following requirements:
-Vin: 20-32VDC
-Vout: 110VDC @ 3.2A
When using…
Hello,
If the inductors are getting hot then those are the devices that need to be changed. Taking a second look at the datasheets it looks like the temperature rise is only specified for the DC current and not for the RMS current. This might be a sign…
Hello Ken,
Please provide the TI part numbers for the devices being used.
Did you look at the waveforms before applying load?
When turning on switching supply prototypes, the waveforms will tell a lot about how it is functioning.
Regarding the LM5155…
Hello,
Thank you for considering the LM3481 in your design.
I think given your power requirements, you can use the LM3481
Yes, there are some designs that can be used to output 24V @ 2A from your input ranges. I would recommend taking a look at PMP8536…
Hello Kartavya,
Thank you for considering TI products. I am not fully clear if I understand your question the right way. At the moment I would recommend to have a look at the LM5155 boost EVM
The output voltage is not at the level you need, but can be…
