TPS54202: What is the current can let TPS54202 exit the ECO mode?

Gust Zhang

Part Number: TPS54202

Hi Team,

Tps54202 has the ECO mode, my question is that how much current can exit the ECO mode？

Best Regards,

Hi,

The output current for mode change depends on the input voltage, output voltage, inductor value, and the switching frequency.

Please help confirm the above value , so we can calculate this margin current .

Hi Young,

Can you tell me about the calculation formula? My customer wants to know the current that can exit the ECO mode.

Best Regards,

Hi Gustc,

You can use the formula below:

Iout1=0.5*Fsw*[L*Iskip*Iskip/(Uin-Uo)+L*Iskip*Iskip/Uo].

When Iout>Iout1, it will exit ECO mode.

Let me know if you have more questions.
