Other Parts Discussed in Thread: TPS55288, LM5176

Hi,

My customer is looking for a step up DC/DC solutions with the following conditions:

  1. Vin is 5V to 20V
  2. Vout is 12V / 3A.
  3. if Vin is 12V or higher, the input can be connected to the output directly and by-pass the DC/DC.
  4. Small footprint.

Is there such a solution available ?

Regards,

CM.

    Dear Sir,

    A buck-boost converter can meet yo requirement.

    You can use LM5176. OR if the schedule is not in rush, you can choose  TI new part TPS55288. But this part has not been released yet,  just has sample. You can contact with the TI local FAE for help if your volume is big.
