WEBENCH® Tools/LM5010A-Q1: Webench or online calculator

Hi, 

Which values are different? Normally they should be similar. 

If you are unsure, i would also check with the EVM against the two tools and see which one is closer. 

Thanks

Hello,

Values of inductor, resistor and switching frequency.

Hi Timur,

Could you attached both the webench design as well as the calculator?

Thanks

Hello Arief,

Please find attached calculator file and printed report from Webench.

Hi,

It looks like the value of inductor looks ok for both as well as the output capacitor on webench recommend 2x10uF and calculator is 24uF. 

In this case, i would check the webench design with an EVM and test the design. 

Thanks

Hello,

It is hard to compare EVM with Webench design: 1. It does not allow to have that small input voltage, so I had to go to 7 V; 2. It does not allow to set switching frequency at 200kHz and the maximum allowable is 135kHz, but in fact when I set up 135kHz in the design it showed 160kHz in the report (see screenshot). Can you please check files I send and also comment on Cin and Cout values?
