LMR43610-Q1: Could you please help to test the light load efficiency (10uA~800uA)?

Hi Iris,

Please allow me some time. 

Best Regards,

Hi Iris,

Still working on this.

Thanks

Hi Youhao,

Thanks and waiting for your update.

Hi Iris,

Our team is preparing the set up for the tests. I expect to have the results in the next couple of days. I will share with you as soon as I receive the results.

Thanks,

Youhao

Hi Iris,

Sorry for the delay.  Here is a quick update to let you know that we have not forgotten this case.  We have assembled a setup able to measure efficiency at micro ampere load, and we also found an EVM and also swap the IC with an LM43610 and tested according to customer's load conditions. However, the IC variant in hand sets the frequency to 2.2MHz.  We are getting the variant able to set the frequency to 400kHz and will re-test.  I believe with the oscillator sets to 400kHz, the IC would draw less current and result in higher overall efficiency. The IC should come early next week and we should be able to share the results soon.

Thanks,

Youhao

Hi Youhao,

Thanks for your update. Please go on.

Hi Iris,

Thank you for being patient.  I will update as soon as I get the new results at 400kHz switching.

Hi Youhao,

Got It, great thanks!
