Hi, We are designing with the AM3352 and TPS65217C PMIC closely matching the BBB. We have two power inputs (Primary and backup) coming from different PS. We intend on connecting the primary to the AC input of the TPS65217 and connect the backup to the USB input. We do not have a battery in our system and need to the TPS to auto switch between the AC/USB sources when the AC input is lost.
TPS datasheet section 9.3.9.1 says that it is not recommended using this mode if the battery is absent. I checked with TI who said that this mode, while not recommended, has been widely used and is also on the BBB. TI suggested posting my question on the BBB forum to see if anyone has had any issues or Lockout conditions when using the BBB or their custom design in this mode. I will appreciate if anyone can share their experience in applications similar to mine? Thanks in advance. -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.
