LMR43620-Q1: SW Freq. vs Out I[A]

Hi,

We don't have data for this, but the nature is the following: as load current increases the SW frequency also increases. Also, an you please let me know why do you exactly need this plot, so that I can help with some other option.

Thanks,

Hi ,

I want to know frequency of load current we use.  about 500mA. 

Thanks

Hi,

PFA the attached excel that will give you frequency for corresponding load current. I have taken values for the EVM.

Vin = 12V

Vout = 3.3V

Ipeak(min) = 0.27

L = 3.3uH

FSW in CCM = 2.2 MHz
