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…
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…
Part Number: LM5121-Q1 Other Parts Discussed in Thread: LM5121 , LM5069 , LM5122 Hi,
In LM5121,Shall I put bulk capacitor after disconnection switch?
So that I can limit my input inrush current due to Filter capacitors.
By doing so,Will it affect…
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 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…
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…

Im trying to understand how the tool selects parts when it does the automatic selection. I tried 4.5Vin 9Vout…
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: LM5121-Q1 Other Parts Discussed in Thread: LM5121 We are using the LM5121 on a pluggable board to convert -28V from a chassis backplane to +12V. The +12V feeds two other DC-DC converter to produce +5V and +3.3V. The +12V output is fairly…
Part Number: LM5121-Q1 Other Parts Discussed in Thread: LM5122 , LM5122-Q1 , LM5121 Hi,
I need to make a proposal for a power supply section, dedicated to an automotive audio system.
The most critical conditions are Vin=10V, Vout=34V, Iout=20A . …
