Part Number: LM5121-Q1 Other Parts Discussed in Thread: LM5121 Hi,
I am going to use LM5121 for 5V to 10V@6A
Can we use series disconnection switch Rds,on for current sensing instead of Current sensing resistor to reduce the component and converter size…
Part Number: LM5121-Q1 Hello,
I want to make an isolated flyback converter using the LM5121-Q1 IC. I have a requirement of the output voltage of 100v and 4A DC and I have the input of 48v 9A from the solar panel, so I need help that can I make converter…
Part Number: LM5121-Q1 Other Parts Discussed in Thread: CSD16340Q3 , BQ24640 , CSD17577Q3A , , LM5121 Tool/software: WEBENCH® Design Tools Hi,
Im trying to understand how the tool selects parts when it does the automatic selection. I tried 4.5Vin 9Vout 6Aout…
Part Number: LM5121-Q1 Other Parts Discussed in Thread: LM5121 , LM5155 , BQ24640 Tool/software: WEBENCH® Design Tools Hi,
I would like to use LM5121/-Q1 in my design and use Webench to confirm. My design will have external Vin supply of 5V and it should…
Part Number: LM5121-Q1 Other Parts Discussed in Thread: LM5121 Vin is 27 to 55
Vout is Vin to 65
Lin is 4.1uH
Rosc is 43K or running about 208Khz
Cout is 10,000uF
Inrush limiting works fine, safely charging Cout to Vin, However Boost operation above Vi…
Part Number: LM5121-Q1 Other Parts Discussed in Thread: LM5121 Hi,
When we make the detailed design procedure of LM5121, we don't understand the equation (30) and (31) in 8.2.2 Detailed Design Procedure.
Could you please what is Iripple_max(cout)?…
Part Number: LM5123-Q1 Other Parts Discussed in Thread: LM5121 , LM51551 Hi,
I've tried to design boost converter using LM51551 and LM5121 without success and decided to give LM5123 a try. I've used both Webench Power Designer and Power Stage Designer 5…
Part Number: LM5121-Q1 Other Parts Discussed in Thread: LM5122-Q1 , LM5121 , LM5122 Tool/software: WEBENCH® Design Tools I don't find max output current or max power dissipation of lm5121-q1 in the datasheet, but when I use webench tool, I set the output…
Hi Harry,
just an old habit, I've used it once and it worked, so I decided to use it again. Are there significant differences between LM5121 and LM5122 besides lack of disconnect switch and freewheeling diode in LM5122 on the favor of clock sync? If the…
Part Number: LM5121-Q1 Other Parts Discussed in Thread: LM5121 Dears:
How could we use webench to simulate LM5121-Q1 under 4.5V-30V input, 8V at 14A output?
We must let the Max input Voltage is lower than output Voltage and the Webench will give a design…
