Hi,

 

I'm powering my board from 3.6V lithium battery, and right now I'm using a 3.0V LDO to power the MCU.

I guess its not the most efficient way to conserve energy.

Can anyone recommend (and maybe provide reference design) a buck converter design?

I'm have some concerns about noise and etc.

Any recommendation?

 

Thanks

Ariel

    Hi,

     

    Thanks, It slipped my searches.

    Can someone recommend, based on his actual experience, a good choice for a DC to DC converter to be used with the CC2510 (I only found for the CC2500)?

    I understand that I should choose one without the power save mode.

     

    Thanks for your help

    Hi,

     

    Thats for your reply.

    The TPS62231 it a fixed 1.8V converter,

    And the CC2510 data sheets specify a min. 2.0 V supply.

    If I got it right, the CC2510 have its own internal converter that step down the supply to 1.8V

    So I just want to make sure that I can use the 62231 even thought its 1.8V output and not 2.0V, (Its a perfect fit for some of my other board needs)

     

    Thanks,

     

    Ariel

    Hi,

    There are different fixed output voltages versions available from 1.0V to 3.3V so I would recommend to use 2.1V or 2.0V version.

    Regards, Richard.
