LMR50410-Q1: Webench simulation of LMR50410X

Danilo A.

Part Number: LMR50410-Q1

Hi Team,

The customer simulated LMR50410X in Webench with input voltage of 24V, output voltage of 5V and 1A output current. However, the simulation below shows that the output voltage is 4.4V only. What could be the caused of this error?

Regards,

Hi Danilo,

I understand your confusion. I 'm unsure why the DC value shown on the schematic do not match the final values shown in the waveforms.

Look at the output window which shows the simulation waveforms and notice that the waveforms ramp up to VOUT = 5V.

I will look into this and report back.

Regards, Jason

Hi Danilo:

below is my simulation result, how the waveform shows in customer side?

Hi Danilo,

The voltage values in the schematic are the bias point values calculated by Simulator at t=0.

Bias point is calculated only once at t=0. You would need to plot the signal to get the values of the signal.
