LMR16006Y-Q1: Feedback pin leakage current? or what is the limit for RFBT and RFBL resistors?

Hi Yossi

The IFB_leakage is not seen in the LMR16006 datasheet. The external feedback divider values can be calculated the same way as for a buck. Normally no larger than 1M.

What is the end equipment and the application needs here? Is the automotive grade needed? Would you consider LMR51610 , It is synchronous, 65V, 0.6A Buck converter. IFB_leakage=0.2nA.

Thanks and best regards.

Hi Gui He,

Thanks for your reply.

The application is automotive. A Maximum of 50mA.

I used the LM5164-Q1 in the first prototype and it worked fine but I would like to have a smaller solution at approximately the same efficiency, and the LMR16006 provide good results in simulation.

I  don't want to lose power on the voltage divider, so I think of using RFBT as 250K and RFBB accordingly.

Regards,

Yossi

Hi Yossi

Well noted. You can also take a look at our newer devices LMR36503-Q1, and LMR38010-Q1.
