• AGND for Parallel LTC3310S

    /When using two LTC3310S regulator, is the AGND shared between the master and the slave regulator or does the master receive its own separate AGND and the slave its own AGND?

  • LTC3310S footprint

    Hi 

    In 3310 D/S, title is LQFN but p.26 package is LGA.

    And in SUGGESTED  PCB LAYOUT TOP VIEW,  expose pad footprint don't have size information.

     How long these PCB are ?

    Best regards 

    Thank you very much.

  • RE: LTC3310, 0,85V 6A power supply

    Hi Bruno,

    The biggest difference between the LTC3310 and the LTC3310S is that the LTC3310 does not have the small caps on the VIN to PGND pins and the VIN to AGND pins. The LTC3310 does require these three caps to be placed as close to the VIN to PGND…
